Jim,

Those transformers used to be as common as dirt (actually, they matched the
6V6 to 3.2 ohm out. The 8 ohm speaker is of more recent vintage ). If all
else fails, try a 6 volt transformer, the kind you might find inside a large
power cube or a straight filament transformer. The best match for 5K to 8
ohm impedance is a 25 to 1 voltage ratio. If you chance upon a 5 volt unit,
so much the better. Center tapped 6.3 volt filament transformrs are great
since the center tap gives you a choice of impedance match. Get one that
will handle an amp and you will have plenty of capability. Your 6V6 will be
happy.

The hi-fi purists will jump all over this suggestion, but will be unable to
tell the difference in an objective double-blind study.
