14 years later, I've decided that I want to keep my 808 pots and  
hopefully find some more:

need the following:
5 100k A level  pots
2 100k B Snare Drum Tone pot
1 5k Cowbell level pot

I am also trying to determine the rest of the values for some of my  
intended mods for basically Decay and HPF / tone control of every  
other voice.

If any of you have figured out what resistors are the following:
D55, D57,D59  = Low, Mid, Hi tom decay
D61 / C24 = Claves / Rim shot decay
D69 / Q 69 = Maracas / Hand clap decay
Q68 = HPF of Maracas / Hand clap
iC 2  / D2 C9 = Cow Bell decay / filter
Q 26, Q 28 = Open & CL hh tone / decay...

would love to replace them with more of the same type pots so this  
thing looks good!

Also need 2 80017A Roland ICs to finally get my MKS-7 to work..


Thanks!
