Someone recently gave me a Lux MQ3600 power amp. Unfortunately there is one
8045G power tube missing. Finding one seems impossible by my search. Does
anyone have a source for them? Beyond that, has anyone done the mod
described below and want to comment on the expense and/or result?

*8045G--power triode, made in Japan by NEC especially for a 1970s-model
Luxman amplifier. Long out of production, scarce and expensive. Unlikely to
be manufactured again. There may have been a version marketed by Golden
Dragon recently. We recommend having the amplifier modified to accept a
triode-connected EL34 or KT88. This may be a difficult and expensive change,
though less expensive than finding new 8045Gs. Please consult with an
experienced service technician.*

Thanks, Ken
