I picked up a toroidal transformer cheap but not sure fit its suitable.
Specs.
160.va
Pri . 2x115v/50Hz
Sec1. 0-280v-320v-350v/0,35A
Sec2. 6.3v/3.6A
Sec3 6.3v/1A
Sec4. 50v/0,04A

Any help would be greatly appreciated.

One EL34 draws 1.5A heater current
One 12AX7 draws 0.3A heater current.

w/o calculating exactly - forget the PT, it will become toast

The fault almost always is sitting in front of the amp :wink:

Thanks for the reply
so I could use it for a 50w version using
2 x el34
If I'm right would be 4.2A draw
