I picked up a 76A some years back that looks almost new some years back
and even in very good shape they seems to be presently running no more
than a $1000 to $1200 for a mint 3 holer and often less.

I haven't seen many going for that on e-bay. The ones with the initial
bid of $1200 or higher just seem to set there with no bids.

You still have to shoehorn in a filament transformer and remember not to
cook the HV transformer by driving the 3CX or 3CPX800s to their maximum
plate current. To me, mounting the new filament transformer on the back
of the amp is not an option. You can get a plate transformer with the
higher voltage and proper filament winding, but the amp conversion just
got a lot more expensive.

They are a nice amp, but few would pay more than about $1500 for one but
there are exceptions. OTOH there may be one of those exceptions out
there looking for just what he has as it is a beautiful example.
There are a nice amp, but they are also incomplete for today's ham and
ham bands. If a ham can afford to pay over $2700 for an out-of-date
amp, no mater how nice, they likely can afford to purchase a new amp
with all bands, QSK, and enough overhead to run digital 24 X 7.
