I ordered the valves from Hotrox and they arrived the next day, so thumbs up for quick delivery, but i went on holiday that week so i havent yet had chance to replace them and see what they sound like.
Ironically the hum has since dissapeared (either that or my hearing has ) so the urgency to change them has gone.
I'll probably replace the Jmp-1 valves first to see what that does to the sound.
