[sdiy] On the topic of ring modulation (Using FETs instead of diodes?)

[Paul Perry]

Some insight to diode ring modulators:
http://recherche.ircam.fr/pub/dafx11/Papers/66_e.pdf

and you can still buy PCBs from Ken Stone

though you will need to find your own transformers.
On the bright side, checking various transformers and diode types can be 
fun.
