Hello,

I am getting a slightly higher B+ voltage (~ 326.3V) than what is recommended in the manual. My incoming A/C voltage is 120.5V. From previous posts regarding this issue, it should not be a show stopper and I can move along. But just wanted to confirm once more.

Thanks!

Yes, I would go ahead and keep building. Just be sure that the incoming AC wiring is hooked up properly for the instructions for that voltage range in the manual.

Thanks Paul! Yes.. the transformer windings were done correctly. There were no issues also in the power transformer secondary test. I was getting 9.48 VAC and 119.6 VAC there ...
