Hi,

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

http://www.schematicheaven.com/fende...er_60_rack.pdf


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.

HVCA can supply samples, and if you only need two, it may be possible to get
them this way.
