Hi,

I need to replace the 2 reverse biased diodes connected to the OPT on a
Fender amp, as in this schematic:

They are R3000 diodes, 3KV @ 200mA. Unfortunately I can't find these in the
UK, so am wondering what the design requirements of these devices are and
whether I can substitute something else, maybe 3 1KV rectifers in series.



Cheers,


Gareth.
