No numbers, or ratings in the manual?
I do have a manual, out in the shop...some where...
If not, I could fire mine up and take some measurements.  I doubt it exceeds
12 VA.  Probably even smaller.

I miss my old tube manual...I could look up the ratings...I think they are
12AX7s, or similar.  12AT7s are the same tube, but with higher gain.
I's been so long since I looked, I don't remember which tubes are in there.
Probably two dual triodes, a tone generator and audio amp (dual tube) and a
rectifier.

Guess I'm going to have to get the thing out and see what's there.
