RE: I have output transformers for 6B4s/2A3s

Posted by Ralph on August 22, 2007 at 15:10:53:
The 6CA7s in the ST-70 are looking for about 5K; the 6B4 wants about 3K.

The screen taps are therefore more appropriate for the 6B4s- I would try that out and see if that gets you the power that you are looking for!

If you want a good quality output transformer optimized for push-pull operation with this tube, I have a nice one all sorted out at a reasonable price.
