Moody PRS Sonzera 20

[Neil Forsberg]

Hi folks!
Got a "moody" 2023 Sonzera 20. A couple of months ago reverb and presence just died. I got it repaired at a sertified PRS service centre. And on monday the amp started to shut down and back on again, this repeats in 1 to 5 minute cycles. There are "light" in all six tubes but power on/channel select leds turns off. Yet, i can still hear the hizz from the speaker..
I have replaced all tubes, no difference.
Any ideas?

My unwanted and unsolicited idea is that PRS should not be making amps in China.

Sounds like a capacitor loading and unloading

 

[Neil Forsberg]

Yeah, my thought as well. Thanks for the reply

Neil - Any follow-up on your amp? I'm about to drop $$$ on a low wattage tube amp and I'd love to know how this turns out!
