I have an old Orange 120 watt head that came with Mullard EL34's. They need replaced (only running a pair) and I don't know what I can get to replace them. I tried a quad of SED's and they work until the volume is past halfway then the mains fuse pops. With the pair of Mullards, the fuse won't pop and the amp works fine.
Biased at 32 -34 ma the PV's are approx 520 with the screen being 1 volt less.
How about the GT 6CA7's? That's what I am leaning towards a t the moment....
Thanks,
George
