Got the EI plates out and unwound the secondary but the primary is so small and fragile.
That may be a lost cause though.

Measurements show 3.2 ohm on the voice coil with the bucking coil. From a few minutes of research shows 10,000 ohms or so for the secondary P to P.
So That would be a 50:1 transformer that can handle 5 watts audio.
New is out unless it is cheap.

With P-P 6F6, running at maybe 300 volts on the plates----it will be MUCH higher power than 5 watts !! More like 12-15 watts. Like I said--a 15 watt tranny will work fine.

This likely will work. 42 tubes are the same electrically as the 6F6 tube ::
