ST70 power supply question
Posted: Mon Sep 12, 2016 1:58 am
I would like to build a st70 clone from scratch.
Ok, i need to clarify a few things about the power supply. I'm planning to run the amp with kt88 tubes.
So, i'm going to order the PT locally, it will be a toroidal. So i need to confirm the power ratings:
2 x 6.3v heaters at 5A each with center tap
1 x 720VCT (360-0-360) at 300 ma with 55V bias tap - should i raise the current rating for this winding to say 400ma?
1 x 5v at 4A - no center tap
Thank you.
