Savin the Yamaha CS-80 (6) SH Sample and Hold Module


YouTube via gavincurtis
"A series of videos showing the ground up restoration of my ailing CS-80. Working CS-80's are playing music on borrowed time as their 70's era MOS, armadda's of deteriorating digital ICs and leaky electrolytic capacitors take their toll on these grand machines. This video covers restoration of the SH (sample and hold) control board. Parts used in each video are available in kits on ebay. Each kit covers a particular module in the CS-80 so other people can restore their vintage synth. Music is a CS-80 is from the great animated "Starchaser" movie soundtrack."

    At least, on the subosc, "random" could be chosen, but it produces a noise, not a slow S/H.

    since it's written "noise" on the subosc, i expected it to be just an usual noise generator, not a so complicated circuit
