Hello Nate,

Sorry for the delay in seeing this!

Your output transformer would be just fine.  You simply wouldn't use the ultra-linear taps... or you could use them in place of the 1K 2W resistor on each output tube, your choice.

Hi.

Not familiar with the zkit1 board, but in looking at the picture the ul connection points go no where on the board.

To wire this up you can omit the 1k and connect the ul lead to pin 9 on each output tube. Maybe where the resistor would go? I just looked at picture in documentation.

I have used the zkit2 board. They are very well made so you can certainly experiment by soldering in resistor to try each way. Many times if you are careful removing parts.

I put a dpdt switch in my circuit so you can switch to ul mode.

My feeling after listening each way, the ul taps create more power/louder. Using 6n1p output tubes, me experience was that running the tube this way created more “fatigue”. Maybe different with other tubes and systems... I preferred the 1k resistor, no ul tap. It keeps tube in triode mode as I gather.

Hope this helps!
