Unhappy Help! Building Jax's HFTA

Hi all!
I'm building Jax HFTA. It have been a fun project and everything seems to be working fine. This weekend i trimed everything as Jax's tells in his instruction.
I had 140 V at V1A and V1B anodeplates. 252 V at V2A and V2B anodeplates. So everything was a go for some testmusic

It played well for about 15 sec then the sound was very low, i raised the input signal and listen very close to the speakers, i couldn't almost hear anything.

I started to look for what was wrong. I messured that V1A and V1B anodeplates suddenly was at 299 V and V2A+V2B anodeplates has about 438 V..
438 V is whats comes in on B+2 from netagg.

Anyone know what can be wrong?

Thanks! //Daniel
