[sdiy] Radfio Shack

[Rude 66]

speaking of 'le shack':

does anyone have the schematics of their little 'electronic reverb' box? i
picked one up on my recent visit to the US at a flea market, but 3 of the 4
sliders don't seem to work. it's based on the mn3207/3102 bbd's and 2 6552's
(opamps?)
it works, gives a delay, but no variables in the sound can be made (no of
repeats, depth, etc..).. and the mic in/out is very distorted, so maybe one
of the opamps is shot..

anyone?

thanks!
