Christian, did you adjust the DC output by dialing back the AC on your Variac ? I’m curious if that is a recommended method? I see a lot of tube based DC PSUs with fixed voltage. If I could adjust the output by restricting the AC they would be useable for my FC drivers which need around 150VDC.
Hi! Sorry for the late reply - I missed that! No - it's not that easy. If you regulate the AC voltage of the input on the power supply, the heating voltage of the tubes also changes. The regulation should be done on the secondary side.
hello sir i have field coil speaker with 2000 ohms of field coil and 2 ohms voice coil. what should be my DC power supply (volt and amp) to feed my field coil ?
I can't imagine how good it sounds
Thanks for bringing this ole gal back to life!
Sounds amazing.
Constant 28W draw is a lot. Doesn't it get hot?

@@Monodyn thanks for setting me straight on that.

Hi Manu,
you can try it with around 100 Volt DC , so at 2000 Ohm fieldcoil its around 50mA .
@@Monodyn thank you for reply !

Hi , it’s gone some time ago 😌
@@Monodyn thx very much. M.
How much and where are you? What branded?
