Hello List,
Well, I have just about given up on figuring out this ARP 2600 ring mod
submodule. Because the transistors are glued together, I still have no idea
which of the transistors are NPN and which are PNP (except for the few on
which the part number is visible), and I haven't been able to find out the pin
orientation for the TZ81 part. So I'm hoping that one of the list memebrs who
has already figured the circuit out could send me a copy of the schematic,
either via email or by postal mail. Can anyone help?
BTW, I unpotted a defective 4015 Sample and Hold submodule, and was successful
at exposing all of the circuit. Once I got it open, it was an easy fix - a
bad LM301. It works great now. I have made a schematic of the circuit, and
I'll be happy to send it to anyone who wishes to see it.
