I have a marantz 4230 receiver with a blown amp
looking for a SV-3a temp compensating diode (or an entire amp board)
Can I use any temp compensating diode or is there something I should be
looking for
Thanks
Bob

The NTE177 is a sub for that diode, which appears to be an ordinary 200V
silicon rectifier. You can probably use any rectifier with the same case
as your original part.

thanks the only thing odd I noticed is that the SV-3a diode doesn't look like
a diode using a dvm. i.e. looks open in either direction
They do look like diodes when I put them on my huntron tracker which had me
wondering if there were two devices in the case or something that might raise
the forward voltage drop
I have a few diodes from a old scott receiver that I'll try and see what
happens

See this schematic:
http://www.jmargolin.com/marantz/p750.pdf

Diodes H005 and H006 are identified as "HV0000212, SV-3A". The circuit
symbol for each diode is two diodes in series.

However, the schematic diagram for the Marantz 4240 receiver draws
them as regular single diodes.
