Particle accelerator cut out

[Audandash]

I will post pics in a little bit when I pop it open I just wanted to go ahead and ask while this was fresh on my mind. I was playing my c2c particle accelerator earlier and it sounds great! Everything works as it should. Once I hit about the 15 min mark it shuts off and won’t pass signal. It still works in bypass but that’s it. After about 10 mins it will start working again. I don’t feel comfortable poking around while it’s hot since it’s a high voltage circuit but I am thinking I have a bad joint somewhere I need to find. It’s almost like it gets hot and needs to cool down. It’s not the enclosure or anything since it’s one from Nathan. Anyone come across this before have any other ideas? I realize you need to see it but it’s more of a curiosity thing at this point.

Well I reflowed a bunch of stuff for good measure and noticed a suspect joint on the tube board. I have been playing past the 15 min mark now and it has not cut out so that must have been it.

Nice beefy psu supplying it? A psu going into thermal protection would've been my first guess.

My guess is a bad joint. If it shows up again, check to make sure that component voltages are not being exceeded (I’ve had some poly caps that were close/under the voltage - didn’t notice! - and it might be a problem). Last ditch would be a tube hitting a weird thermal thing.
