Does anyone know of a source for power zeners? I lost the bias zener in an
old Kenwood TL-922. It's 7.2 volts at unknow watts, but it carries both
grid and plate current which could total near an amp, so it's likely at
least a 10 watt device - and it looks it. Kenwood says it's discontinued,
and it's replacement, a "ZX7.5" is $49.70, and I'm hoping to find a less
expensive solution. It failed when a 160 volt electrolytic blew up and
spewed foil around the base of the control transformer, and I think the
zener got a dose of 110 v to ground - the amp was sitting in idle mode at
the time. Thanks for any suggestions.
