Hi,

what is the purpose of the reverse biased diodes on the OPT/Cathodes as in
this Fender circuit?

I need to replace a faulty one and am having difficulty sourcing the part
Fender use (R3000). Does this need to be a specific type of diode or can I
make up the 3kV diode required using standard 1Kv rectifier types?


Thanks,


Gareth.
