Hi All,

I have a Luxman SQ-38FD Integrated valve amp.
The output tubes are 50CA10 and practically imposable
to get hold of (and way above my budget)!

I believe that this amp can be upgraded to use EL34s
and Luxman still make a version of this amp using
EL34s, called the SQ-38 Signature.

Does any body know of such mods, or have the schematic
for the SQ-38 Signature. I do have the full schematic for
the SQ-38FD.

Hi Mohan,

Thank you for your kind offer!

The amp actually belongs to a friend of the faimly.
His plans have changed and it looks like the amp will be
going into storage for a while and he will look to do any
upgrade then.

It also needs some other work, all the Caps (electrolytic)
are going/gone and some corrosion (it was not stored very
well for some time). So it is probably best to do it all when
it comes out of storage for good!
