Hello - I have these transformers (see attached), and am wondering how to milk the most out of them. I recently built a Plexi6V6, and am now considering a "D" style, for the next.
To get to the point, instead of 6V6 output, I'm thinking EL-34 or 6L6's. But I'm not sure if the current limitations of the transformers is something I need to design around. Or, if I should just copy a standard (2) EL34 or 6L6 design, and it should be fine, just breaking up early.
Thanks in advance for advice, and pointing me in the right direction.

Re: Transformer question
EL34 heater current draw is 1.5A.
6L6 heater current draw is 0.9A
12AX7 draws 300mA per heater.
That transformer is rated at 5A heater current. So, a couple of 6L6 power tubes or a pair of EL34's, and three-or-four 12AX7 type tubes would be okay. However, I guess the output transformer rating/load will play into whether the current drain on the B+ rail would be enough at 150mA.

Re: Transformer question
So, will I hurt anything if I just follow a standard (2) tube push-pull 6L6 or El34 output? Or, will the PT/OT limits naturally keep it from a melt down?

I'll be camping for a week with my son. So, if someone responds, and I don't reply in a week, that's the reason. Thanks.
Re: Transformer question
You're probably underpowered a tad for 6l6s. Try push pull el84s
