Electronic components
Good morning precious forum,
i need to change some component(Capacitors and resistors) in my modular Cotk
My Synth is very nice but i search the my sound.I am interested in companies that sell components similar to that used by the Moog in the 60's and early 70's for the construction of modular, such as electrolytic capacitors and resistors carbonic.
In this link you know you recommend the right company?

Many thanks and see you soon

Re: Electronic components
I'm not shure whether I understand you correctly. COTK build clones with actual components. I don't recommend to replce these components by old ones or by old types. The circuits work as they are. And - the sound of your COTK System wouldn't change if you'd exchange the components. That might even be dangerous for your system.Gaetano Di Giorgio wrote:Good morning precious forum,

The only issue I could imagine is to buy an inductor based FFB (907) from them. This module adds some cool non linearities to the sound because they use real inductors instead of electronic replacements.

Re: Electronic components
Analogmonster, thanks.
I don't search NOS
But a company between these http://www.hificollective.co.uk/componentshome.html or others that produces (components resistors and capacitors) modern but similar to that of the old Moog modular.
Cheers

Re: Electronic components
Sounds to me like you need an actual Modular Moog, and "clones" just don't do it for you...!?
Cheers,
Tom

Re: Electronic components
Hi Tom
I have a COTK; for the same would have to spend € 150,000 if it was Moog.
My modular does not convince me in the filters but otherwise I find it best to Moog, as in oscillators that have a warmer sound and harmonious.
I have to change some component filters, I have already done successfully replaced with orange but not enough.
Stay well

Re: Electronic components
The Moog Sound is totally a subjective thing and though I don't have the slightest bit of electrical knowledge, I don't think you will find what it is you are looking for with just a few component changes, and I agree with analog monster that you probably shouldn't go this route for safety reasons.
What modules do you have?

Re: Electronic components
Hello Erick
With a different electronic component the sound change totally.
Experience!
This is my modular:

Re: Electronic components
Hi my friend!
First I would suggest seeing if just exploring different patching and settings can get you to the sound you seek? Maybe if you can get as close to the sound you want as you can, post a video and description of the patch and also an example of who ever you are trying to emulate (like a Keith Emerson video etc) then someone here might be able to suggest what to do differently that might help you. For instance have you tried feeding the output of the filter back into itself?
Secondly, maybe consider trying a different brand of filter? The sound of Mos-Lab modular tends to be compared to original Moogs a lot. Maybe buy a Mos-Lab 904A and see if you like it better than the COTK C904A? Synth-Werk also makes a 904A clone.
Lastly you can try swapping out components but, this may be expensive and time consuming and not really gain you anything. Be aware that you might convince yourself that it sounds better after your changes but you'll never know for sure unless you start out with two of the same filter that sound identical, change one and then have someone help you conduct a double blind test with several other people.
Best of luck!

Re: Electronic components
Dear John, how are you?
One or two months ago i send you two sounds of my 904 modified by me with orange capacitors...very nice i think.
I need to change also the resistors because in the decay of the filters something is cold.
I need also to change components in one other filter 904 Cotk but in this case i search one brand that built the same components of old Moog modular but moderns.
Please, do you know in this 39 brands who prepare components like old Modular Moog?

If you know a factory in USA that produce resistors and capacitors old Moog style, please tell me.
See ya

Re: Electronic components
Hi gaeM,
I can't remember if I saw the email or not. If i didn't respond I might not of seen it as I had a couple computer problems about that time and my email is still messed up.
Anyways, I don't know what brand of resistors Moog used back then . . .and they may have used several different brands depending on availability and price. As a guess, for the resistors on that site (cool site by the way!) I'd go with the Allen Bradley or maybe the Arcol.
There are going to be problems replacing resistors though if you don't have access to schematics and specifications for both the Moog and COTK modules since it may be hard to tell where 5% tolerance resistors are used and where 1% or better resistors were used. I'd guess that the original Moog modules used a lot of 5% but there may have been more trimmers used in a Moog than the COTK module might use since high precision resistors are inexpensive these days and with higher precision resistors it's possible to reliably build a consistent circuit without a lot of trimmers. You could end up making the module sound worse to you and then the more often you change components the greater the risk that you might damage a circuit trace etc.
I'm no electronics engineer or expert but I really think that capacitors, transistors, opamps and the value of resistors will affect the decay and 'warmth' of a filter a lot more than the brand and composition of the resistors.
I just hate to see you taking a lot of time chasing an elusive rabbit down the hole trying to make minor improvements. You have a wonderful and huge modular and you are a talented musician so I think you should spend your time just making the best music you can! Or, if you have the money just buy a Moog Model 15 reissue to go along with your COTK?

Re: Electronic components
BTW, resistors have an additional color code, aside from their value, on them that identifies their tolerance: silver band 10%, gold band 5%, red band 2%, and brown band 1%. Most common are 5% and 1%.

O M G . . .I'm not sure what I was thinking but apparently I wasn't thinking very well at the time! I know about the tolerance band . . . .serious mental incompetence on my part I guess! Thanks for the correction!

Re: Electronic components
That chart is a little inaccurate. 1% resistors have an extra color band. They have three digits of value, whereas the others only have two digits.thealien666 wrote:BTW, resistors have an additional color code, aside from their value, on them that identifies their tolerance: silver band 10%, gold band 5%, red band 2%, and brown band 1%.
