The speaker appears to be a two-way 6" horn and
a 12" woofer. In the tube amp there appears what
looks like two 6550 power tubes (one each channel).
That is something like 27-32 watts of peak power (in
current technology) to drive those large speakers.


One 6550 for each channel???
Think a mono push pull amp with about 50 watts output,
not unlike a single Dyna Mk. III.

You may be right (mono). No other speaker
is depicted in room.
