A string of Si rectifiers is cheaper and more rugged.

>> Subject: [Amps] HELP: obsolete power zener for a TL-922
>>
>> 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.
