So, the whole backup plan kicked into action at the weekend...it actually took less than a minute thanks to the Helix - amp went down, I managed to swear, pull faces at the drummer and get my "backup" direct preset up within a few seconds and did the change mid-song!!
Anyway, at 1/2 time a quick look over the amp showed me a blown Mains and HT fuse, changed them but it was still not playing ball so decided to leave it and check it when I got home.
So, it looks like one of the Power Valves (Ruby EL34BHT's) had actually blown out - cracked glass around the base, no vacuum left and therefore went to the big valve sanctuary in the sky...
Didn't actually notice this until I tried to check the bias last night - it was lighting up somewhat but had no readings whatsoever..
So, is this just pure bad luck or is there something more sinister that caused this?
The amp is in today for a check-over, revalve and bias but just want to check my facts before handing it over!!

This one didn't it sounded fine and I actually had it running with new fuses yesterday - its only when I decided to check the bias as it was a little quiet in comparison to what it normally is that I noticed the valve itself had cracked around the base.

Its in being looked at now anyway, so hopefully the tech will pick something like this up.
… caused by the amp simply stopping supplying bias, due to the poor-quality jumper connector they use in the circuit. Surprisingly (given that it was a DSL!) after repairing the connector and replacing the valves, there was no other damage.
Your amp wouldn't happen to be a DSL would it…?
