300B amp Power Supply

gorillatube · 06:35 AM

Hello everybody, I am very new to this forum and also new to tube amp world, I am getting ready to build stereo (2ch) amp with 300b, I will be using "Je Labs 300B SE" schematics because it's simple and easy for me as my first project, the question I have is this, do I need 2 separate power transformers/supply/choke or 1 can feed both individual amps?
Thanks for your time.

Hi Gorillatube

I used this for my JEL 300B 2ch and it woorks just fine. I have 230VAC mains so you might have to adjust.

Cheers
