I have a hand wired BF Princeton Reverb type amp made by Klone, a German company.
Sounds fantastic, but definitely needs looking at. I've always been a bit suspicious of one of the power tube sockets as it seems to get very hot around here and one of the Tung Sol 6V6s it came with was blue arching and there was quite a bit of hum. Switched these to Brimar 6V6s really fattened up the sound - this was early last year. I know I should have had it rebiased when I did this but it looks to me like the only amp guy I've heard good things about round here (Pete at SonicFix) has stopped working - or at least website down for months.
When i play through the amp for more than 10/15 minutes now I start getting these crazy static bursts. Thought I had a bad 12ax7 which i switched out tonight - still the same problem...
Any ideas people? I seem to be able to trigger it with lower notes and also touching the power cable where it plugs into the back of the amp.
Here's what it sounds like!

If there could be a simple solution, I'm not adverse to poking around in amps and checking out solder joints etc as have done some basic stuff on Silverfaces before, but did give myself a bit of a shock on a Kalamazoo Reverb the other year so am a bit more wary now!
Thanks!

Would a problem in that area potentially lead to excessive heat possibly damaging power tubes?
It’s been shipped internationally a couple of times since I’ve owned it so that probably hasn’t helped it!

Perhaps the clip will work now?

As an added bonus, I can now experience my Bandmaster Reverb/Vibrolux style combo working correctly for the first time in the six/seven years that I've owned it. It had a very weird problem with the treble pot having no effect which others could not diagnose or fix. But Dave tracked down the issue and fixed it, sorting out some other issues along the way too. It's a strange situation, but now I have to re-learn the amp, as I suppose I had got used to it operating incorrectly! But it's sounding great and Dave turned things around in a week for a price that was far more reasonable than I'm used to. Great to have found such a good amp tech!
Taking my amps in is kind of like going to the dentist for me - I worry about it, so put it off for as long as possible fearing the worst - and a massive bill at the end ... this experience seems to change finally that, cheers Dave!

Yep, they are really great amps... not sure the neighbours back here will agree though!

Side note: this amp has WGS ET65 speaker in it, which I know strays from the 10" format so maybe not for purists, but it sounds excellent!
One thing I've just noticed is that previously the back of the chassis around the power supply input was insanely hot and almost burning to touch even just a few minutes after powering the amp up. Now it's cool to the touch. I'm wondering how I didn't manage to fry myself over the last couple of years!
