New ods124 but have a problem

[Garveyte01]

Hi everyone, first let me just say I appreciate the amp garage community immensely, I am a beginner somewhat, I built the amp but it definitely has an issue I can’t resolve, please watch the video I hope it explains everything well and you can see how it reacts with the current limiter. Thank you

Also I have a guitar sound that is very faint and very distorted

I was having a hard time uploading a video so I broke it down in 2 parts and with a shot of my build

[Garveyte01]

So I reworked my bias pot connection and I have about-35 dc volts on my control grid, but I’m still getting severe tremolo (fast oscillation) and from what I can read on my current limiter it is drawing 30 volts to ground

You might have to swap the OT primary connections.

That was my thought too. An easy way to test that theory is to disconnect the negative feedback lead from the OT secondary.

I hear 120 Hz buzz, maybe indicating a grounding issue. I’d also recommend a good tidying up around the preamp tubes to get it looking more like the layout.

Thank you Martin it was a grounding issue at V1, I’m so glad I found that and now it is working. I’ve learned so much doing this project and then troubleshooting my problem! I could have never done this without the Amp Garage community! Now I’m going to tidy my wiring better. Thank you
