Sorry this isn't actually about a diy amp, but a triode labs. But this is probably the best forum to help me out.
My knowledge is fairly limited here. When I turn my amp on there is an intense "crackle" (the one thats kind of like radio static) that is actually causing major excursion on the driver - enough that I won't be turning it on again.
To me it sounds just like a tube that's gone out, I've heard this before, but I switched all tubes to the other channel and it's still in the same channel. That seems odd to me.
Could this be a bad transformer? Tune socket? Simple cable connection?
I'll have to bring another (cheap) speaker in to try any troubleshooting I guess, but any pointers would be appreciated.

It is new. Yes, that's about what I figured I just didn't want to be missing something stupid before delving in deeper.
Not really, I haven't opened it up yet and no schematic. The designer isn't far from me so I'm waiting to hear back from him on best course of action. A leaky capacitor seems possible...
Switch driver tubes from left to right (and from right to left) and listen again. If you hear the cracling noise in the other channel it’s one of the tubes.

My thought exactly. What are you doing here and why don't you reach out to the manufacturer?
The thing is new. Even if we were to nail the reasons for the issue would you be able to fix it w/o breaking something else in the process? Also, resale value will drop since the amp has been messed around with.
BTW what amp is it? 2A3? 211?

Or a bad tube. I would just get them to diagnose the issue. What amp is it? Just curious. 🙂

Sorry, I meant the sound was new, not the amp, which is around 10 years old but new to me. They are relatively close to me but still a would be a day to go drop off and a day to go pick up so wanted to make sure I wasn't missing something stupid.
Aaaannnnyway, it just went away. It was pretty intense so not sure how. I swapped some tubes using an old speaker so I didn't blow mine. Sound went away. Put old tubes back in, sound still gone. Dirty socket or something? I dunno but it's gone.
The amp is a triode labs parallel 2a3. It's a 1 of 1. Absolutely fantastic amp.

Yes, probably a dirty socket. Some DeOxit and pipe cleaners would help make sure it doesn't come back. ;-)
