hello all, hello ivan
 
just a couple of quick questions about the ring mod circuit
firstly - what sort of transformers are needed (i have a pile of balancing transformers around somewhere)
second - what sort of diodes 1N4148 for instance..?
 
cheers

Anyone here know of a good (available) substitute for the Stancor A-4713
driver transformers used in the classic ring modulator circuit (see attached)?
