Finished building zkit using 5U4 rectifier  325AC/430DC and getting 415 vac at the 1k resistor and zero voltage at the 150 ohm resistor. I have tested all the capacitors and resistors , not sure what to look for next.

I have posted some pictures of the board top & bottom

Which power transformer do you have, considering you are not having ZKIT SS rectification?
Nice build by the way

What are the specs on the secondary taps on that one?
Asking because of thinking that my next build will be with tube rectification. But was thinking of the voltage drop compared to SS, and if I need to step up from the Hammond 300-300V a I have now.

@ Svartemarten: Typically you would use the Hammond 272FX or the 372FX, which is the same except for the dual 120/220 volt input. The power comes from the yellow/black center tap, which is around 300V loaded.

@dixieusa sorry if I caused confusing and bumping your thread, that is about your issue and not about my transformer questions.
Let's keep this thread about your issue.


(@gilf I have the Hammond 372HX, and will be having SS rectification on the present ZKIT build. But for my next build, point-to-point with tube rectification, I was just generally thinking on any potential voltage drop going from SS to tube rectification and if that potential drop would affect the amp's performance. but we can move that to another thread)
