For technical support on all Oakley projects please now refer to the knowledgeable and helpful Oakley Sound Forum which is hosted at ModWiggler.com. I do not provide official building support for Oakley projects, but I am usually available for help via the forum.
What is the difference between Oakley Sound Systems and Krisp1?
Oakley Sound Systems is a small company specialising in the design and modification of analogue music synthesisers. Oakley Sound sell printed circuit boards (PCBs) and some electronic parts to enable people to build their own electronic music projects. This website is run by Oakley Sound Systems.
Krisp1 is a separate company selling pre-assembled Oakley modules. Krisp1 is run by Paul Darlow and his website is here.
If you would like to purchase any parts sold by Oakley Sound then you can do so via my ordering page.
Do you do ready made units?
Official ready built modules in MOTM, K1 and MU (Moog Unit) formats are available from Paul Darlow at Krisp1. See here for contact details or visit the ordering page.
Do you sell whole kits?
Neither Oakley Sound or Krisp1 are planning to sell full DIY kits. However, some component kits are on offer at Synthcube in the US and Elby Designs in Australia.
Do you supply ready made cases?
Paul at Krisp1 doesn't sell cases individually but he is able to supply complete 5U Oakley modular systems which include a case and power supply.
For studio and home use you should also consider the cases from All Metal Parts in the UK as they have a good range of flat pack 19" rack (ie. 10U wide for 10 single width MOTM format modules) 5U, 6U and 10U metal cases with rack rails to the front and rear of the case. As an example their 5U high, 300mm deep case is part number AMP05007. They can also supply blank panels (eg. AMP130045) for any rear mounted power supplies and pairs of rack rails (AMP31002) for mounting your modules. I recommend 200mm deep cases for use with the recommended external 'line lump' power supplies, while the deeper 300mm ones should be used for internally mains powered systems.
To mount standard Oakley MOTM format modules into a 19" rack you will need a pair of either All Metal Part's AMP31002, Krisp1's 5U mounting rails or Synthcube's MOTM 19A rack mounting rails, for every 5U of height.
A 5U high 200mm deep 19" steel case from All Metal Parts. Front and rear rack strips are fitted to allow the module rack rails to be mounted on the front and a power supply panel to the rear.
Unless you need a very shallow depth for horizontal work then for Eurorack systems I recommend again using the steel cases available from All Metal Parts in the UK as they have a good range of flat pack 19" rack (ie. 84HP wide) 3U, 6U and 9U high metal cases with rack rails to the front and rear of the case. The modules are then held in place using 84HP mounting hardware such as 'Z rails' and 'Z ears' from TipTop. Although wood cases look beautiful they can allow excessive heat to build up within your modular unless sufficient air gaps are created, and, unless sufficiently screened, do not stop unwanted radio interference either entering or leaving your modular.

What modules do I need to buy to make a modular synthesiser?
Everyone will have their own preferences so its difficult to recommend specific modules for a complete system. However, visit the Which Modules page for my quick 'getting you started' advice.
Where do you get your front panels?
Either at Schaeffer in Germany or Frontpanel Express in the US. Alternatively, you can obtain excellent 5U MOTM style panels for some modules from Synthcube in the US.
Can I buy the Schaeffer front panels direct from Oakley Sound ?
No. These need to be ordered from Schaeffer in Germany or Front Panel Express in the US. Both companies offer an excellent service. The Frontplatten Designer software is a free download and features secure online ordering too. See the Schaeffer or Frontpanel Express websites for more information. The sales representative at Schaeffer speaks very good English if you do need to contact them direct.
Do you have any older issue PCBs for sale?
No. The only PCBs that I have for sale are the ones listed on the project webpages. If you do need an older PCB, maybe to match up with an older panel design, then please do post a request on the support forum.
Can I buy schematics/PCB artwork for the modules?
I do not sell any schematics for any of our currently sold modules or PCBs. Relevant schematics are only provided for purchasers of the project PCB.
Schematics for most non current Oakley projects are available from Oakley Sound as pdf files for a small fee, although do check the legacy support page to see if they are available for free download.
PCB artwork is no longer available for any of our products old or new.
Are your projects hard to make?
This one is tricky to answer. It all depends on your ability. If you can solder reasonably well, and have the patience to read through all the documentation, you should be able to manage. However, if you rush and find your project doesn't work, that's when you are going to need more electronic knowledge. Being able to read a circuit diagram is an obvious advantage. If you want to get started, perhaps, a good way is to start on something simple. The smaller modules like the Dual-LFO, Fourmix and MultiMix are very simple, and easy to test.
My Oakley DIY project doesn't work, what then?
Join the Oakley Sound Forum which is hosted at ModWiggler.com. Then after checking that your question hasn't been answered you can post to the list for advice. Both Paul and Tony, and many other builders of Oakley equipment, are present on the forum and should be able to help.
Please do not contact me directly regarding building problems or generalised parts enquiries. Neither of us are able to help on an individual basis due to lack of time. All enquiries for help should come through the Oakley Sound Forum.
If you still can't get the completed and undamaged module going and you are in the UK or EU, you may be able to send it to Oakley Sound to fix. You will have to pay for postage both ways, any parts required and Tony's time at 25GBP per hour. Please contact Tony Allgood to organise your personalised 'Get you working' service.
Are all your boards lead-free?
All boards are RoHS compliant, which means they do not contain lead (Pb) . All boards can be soldered with either lead free solder or lead based solder. The boards are finished using a lead free HASL process.
What sort of solder should I use?
All of my current boards can be soldered with either lead free or old fashioned leaded solder. I still prefer to use Pb/Sn solder for my own projects because it is easier to work with.
Who are Oakley Sound Systems?
The company was originally called Sound Systems and was formed by me, Tony Allgood, in 1984 whilst I was studying at university. Initially, it was only a side line to my professional career as an electronic design engineer. However, in 1996, as interest had grown sufficiently in my products and services, I formed Oakley Sound Systems. This, at first, was predominantly a repair business to local music shops and musicians, but the growth of the internet allowed me to start to manufacture and sell PCBs and other products.
In the period between 1999 and 2005 Oakley Sound Systems sold ready made modulars, modules and printed circuit boards direct to people all over the world. My modules have been used in film production, at live concerts and in many hundreds of home studios.
In June 2005 a decision was made to hand over all merchandising to another company whilst continuing to design new products. The retail side of the ready made module business is now handled by Krisp1 run by Paul Darlow. Paul works in partnership with Oakley Sound to provide high quality modular products in 5U MOTM, 5U MU and Euro formats.
In September 2010 Oakley Sound Systems started to sell PCBs directly again allowing Paul to concentrate on manufacturing and selling complete modules. In March 2016 the repair and servicing side of Oakley Sound Systems was closed so that I could spend more time developing new products.
Who are Krisp1?
This is a small company set up by Paul Darlow in 2007 to supply ready made Oakley modules.
What equipment do I need?
The usual electronic hobbyist stuff. The SRE330, ADR30, S-VCO and VCO project, will be the hardest to make, as they require precise setting up. A scope or a chromatic tuner will be very useful, but they are not essential for most Oakley projects.
Can I build these modules to sell to friends?
Of course, you can.
How much will the whole project cost me?
This depends on the case you have chosen to house your project. The case, knobs, pots and sockets are the most expensive items. The quality of these things will set the price of the project.
For 5U Oakley modules, I generally reckon around 50 to 140GBP per module including the Schaeffer front panel. The 5U midiDAC is probably the most expensive module and the Eurorack version of the Multimix is the cheapest.
What is a GBP?
It is the currency of the United Kingdom.
GBP is a short hand way of writing 'Great Britain Pound'. This is the accepted way of writing our currency by the International Standards Organisation when you can't use the ordinary 'curly L' pound sign. Paypal and the webpages on this site use GBP. It should be noted that UKP, although more correct in terms of the countries that it represents, should not be used.
GBP is called 'pounds sterling' on the money markets. It is not affiliated to the Euro in any way.
100 pence make 1GBP. So 6.50GBP is six pounds and fifty pence.
Where on Earth is the United Kingdom?
Not quite a FAQ, but I have had it asked a few times now. The UK is currently England, Scotland, Wales and Northern Ireland. Great Britain is just England, Scotland and Wales. The word 'great' in Great Britain originally comes from an early designation of it being the larger of the two main land masses that form the British Isles.
The UK lies north of France in Europe, but is not connected to mainland Europe. A narrow stretch of sea called the English Channel separates us from France.
I live in rural Cumbria, England, 20 miles from the Scottish border, and close to the Lake District. The Lake District was home to many famous people such as Coleridge, Wordsworth, Beatrix Potter and Ruskin.
Paul Darlow lives in Yorkshire, England. Yorkshire is a huge county which covers the original industrial heartland of England as well as the rolling moors of the Bronte sisters and the James Herriot stories.
What standards do you use for controlling your modules?
VCOs are 1V/octave. Gates are positive voltages above 2.5V. Audio and CV signals are typically +/-5V although can rise to +/-12V.
What power supplies do I need?
For more information about buying or building a suitable power supply for a modular system, please see the Powering Your Modular webpage on this site.
Can I make my SRE330 (or other rack project) internally mains powered?
If you have the skills to do this you probably wouldn't be asking the question. Only fit an internal mains supply if you know what you doing. I cannot endorse this method of powering any Oakley product.
Where do I get all the other parts for the project?
Rapid Electronics (UK), Mouser (Worldwide), CPC (UK), and Farnell/Newark (UK/US). Small Bear (US), Banzai (Germany) and Musikding (Germany) are also useful.
Parts codes for most of the common parts used in Oakley projects can be found in our lengthy parts guide which is found here. This is a PDF document which also contains many Rapid, Farnell and Mouser order codes that you may find useful.
What's the Mouser / Farnell / Rapid (etc) part code for ....
Due to limited time I am not able to answer this question for every part you need to buy. My Builder's Guides and Parts Guide should give you sufficient information for you to purchase all the parts from your own suppliers without too much difficulty. You will also find that the Oakley Sound Forum will be very helpful too if you do get stuck.
Rapid, Farnell and Mouser part codes for most of the common devices used in Oakley projects can be found in the Parts Guide.
What is the form factor of those Alpha or ALPS pots you use?
For the 5U and rack modules the pots I use are the very common 16mm format that is preferred by many modular and synthesiser manufacturers. There is 0.2" between pins in one gang and gangs are separated by 0.2". There are two gangs in a stereo pot and one gang in a normal mono pot. Shaft length varies with supplier but it may be cut down with a hacksaw or Dremel. Shaft diameter is typically 6mm and you can buy them in either slotted knurled shafts for push fit knobs, or smooth round shafts for screw fit knobs.
This is a 16mm Alpha pot with a short knurled 6mm shaft.
All newer eurorack modules use the common 9mm vertically mounted pots.
Do I get a paper receipt with my order?
No, all order documentation is sent by plain text e-mail only. These contain all the details of the order and you can print these off for your own records. All customers are given their own individual customer order number, and I keep a full record of all transactions for around seven years.
