I was a tube amp, and YOU gave it AWAY?

traded off an amp I would never play again for a wurli 112A in 'pristine condition' (for these old hunkers - all the parts are there, just needs a tuning - I can do that!
was a damn good week with that and 2 motorbikes in my hands.

it really is a journey, and you just cant farm out the battle wounds

Well, it had tubes when I got it, much like it had transformers and caps and resistors and even speakers...
I wouldn't call it much of a tube amp any more. Just a nice hardwood box with plastic keys and some grille cloth... I kept all the inserts that had all the resistors and caps and inductors and what not. Good too, because with all that still in there, it would have been very difficult to load.
Here is a recording. Used three SM57s, L and R side of Leslie, and one on 1x12 cab (this one comes in at the chorus). Hagstrom Viking Deluxe into Egnater Tweaker 15 powering both cabs. No EQ nor FX.
Neighborhood power did not go out this time. Guess I'm losing my touch.

I rigged the Leslie amp for guitar use. Type 25 booster amp. Voltages look OK (high) with 410 on the plates of the 6l6gc pair. I put 1v p-p sine wave at the input, goes into the PI. The output of the PI is at 20v p-p. Goes to input grids of power tubes. Plates of power tubes show 80v p-p. Goes into primary of OT. On OT secondary, I get 2v p-p. 40:1 turn ratio, right?

The booster amp works, though it's not suitable as a standalone amp, as it's just a PI and power section. The PT gets warm as it is--I doubt it can support another tube.
Ideas for use?

No. There was a circuit (including an autoformer) to switch the AC to the motor, but I took that out.
But my new, chopped, Hammond organ cabinet, with it's pair of 12" speakers, sounds GREAT. Really wide and full. I'm going to get the AO43 amp working and put it back in the cabinet. This is going to be a handsome "house" combo.
