Darkglass Microtubes 500v2 screeching/static noise issue

[Jim_Dandy]

I've just purchased a second hand Darkglass Microtubes 500v2. When plugging it into my can it works good for about 10 minutes and then an awful screeching/static/interference kind of sound starts happening. I've tried all new cables, speaker cables and a different amp into the speakers and it is 100% the darkglass. The owner said he has only played it at home no more than 10-20 hours max. Never gigged. He bought it brand new in 2022 and when received it is in perfect condition.
I really liked the sound I was getting out of it and want it to work.
Any suggestions what could be happening?

If you aren't using any pedals, and you have tried it with a different bass, it sounds like there is something wrong with the amp. Factory authorized service is my recommendation, or return it if the seller won't help with the cost of a proper repair.

Is the fan working properly? Wondering if the 10 minute thing is indicating some type of thermal failure as the temperature builds up. Good luck getting it fixed, you'll be dealing with Korg
