This 40's [?] Organ Has Many a Tube, and

Of particular interest are the transformers.
1 Jensen Field Coil Speaker Transformer
1 Large PT.
1 Slightly Larger PT.
It has a 'field coil' speaker, many wires, two coils and two amps [one for each coil] as I understand it, I have no intention of attempting to drive the sweet looking 'ol Jensen by rebuilding this amplifier to original, single ended would be fine.
There are rows of 12ax7 only and 12ax7 or 12au7 tubes in the tube field, I guess one tube for each key on the organ.
Of the two large power transformers, one is slightly larger, the ~57 tubes probably have a dedicated heater supply PT.
One pretty, blue Jensen 10'' field coil speaker w/transformer !!!
On the chassis with the two PT's are 6v6's, 6sn7's and 12ax7's, the preamp and amplifier.

At this point, I hope that the rare old amplifiers field coil speaker continues to function for more good fun and long times !
