I read in sci.electronics.design that wrote (in
.com) about 'Reducing

Electronic. I'm guessing it's based around IC706 /707 on the power
board ( http://homepage.ntlworld.com/anengin..._Schematic.pdf ).
Does this look like a very basic delay circuit, or do you think it
should sound like a proper reverb ?

I can't tell; it looks very complicated.
