Hi all, I finished my first Crack build today and cannot for the life of me find the buzzing/humming cause. It's a low-to-mid-level buzz that happens regardless of tubes and regardless of anything being plugged into the RCA jacks, and while it plays, after about 10 seconds there was a loud "Pop," and I turned it off and haven't tried it again. It kept playing after the pop but... yeah. Not gonna blow up anything out of ignorance if I can help it.
Going to go diving into it further once the kiddo goes to bed, but thought I'd lean on the forum here for advice. I have gone through and inspected/reflowed seemingly all, or at least most, of my solder joints, and I followed the Crack Grounding, Tracing the Signal etc. post. All of them came back as properly grounded, although it also says to check transformer terminal 4 to 22, but mine doesn't seem to have those.
