Ring mod circut...

[Hcabnivek]

See below for thread...

This design also appears in Terence Thomas's book  "Sound Synthesis",  a book
that I can not recommend not strongly enough = it sucks.  Full of typos in
circuits etc.  It's a TAB book.
However, this design does appear in this book, and according to him, there are
few restrictions on parts - i.e. any two audio transformers will work as long
as they are matched, and the diodes recommended are 1n914's!  A couple of
decoupling caps are added, and in his version the x input is through one end
of primary 1, the output is at one end of  primary 2, the y signal is input
through the center tap of trans  2 and the other ends of the primaries and the
center tap of trans 1 are all tied to ground.  Basically it's the same.
I have not tried this. I have no idea how (or if) it works, but if it does, as
has been said, what could be simpler?
