Transformers from Vintage PA JCM800?

Post by pleasantbullet »

I have a set of transformers from 60 watt tube PA.
The PA had two el34's, and about 4 other preamp tubes.

I've tested the OT, and come up with 3200ohm Primary winding.
So, I thought that'd be good for a JCM800 build.

The one thing is, the power transformer doesn't have a center tap on the B+ windings. That being said, the PA got its negative voltage from a totally separate set of windings that produced 62v.

I believe the B+ windings is around 400vac (going from memory) its been a while since i tested them.

Would this set be good for a JCM800 with two el34's?

Yes. It would be excellent. The lower voltage amps sound best. 380-420v is a good place to be.

400 Vac on a FWB = 565Vdc
