    Just finished my VTA-120 build, and performing power checks. I’m getting 362 VAC from the power transformer at V1-4&6. Is this too low?

    did you email me about this? I think so, but not sure.
    I believe I got some transformers from our supplier that were labeled incorrectly.

    Yes, I went through and double checked everything and can’t find a reason why the voltage is low. Thought I would reach out to see if anyone else was experiencing this issue.
