Just bought a 50W Seymour Duncan 84-50, 1x12" speaker. SOunds lovely but on one channel, on a couple notes im getting a noise that sounds like a peruvian busker shaking a tin of coke lids...from what I know, this is due to a loose filament on either the pre-amp tube or more likely a power amp tube...
It takes 4 x EL84 power tubes
3 x 12AX7 pre-amp tubes (well 2 pre-amp tubes and 1 reverb tube i think)
from what I've read its fixed biased, so would anybody have a clue what model power tubes i need? I know the pre-amp tubes dont generally need to be biased so i can replace them easily enough, just the power tubes im not sure about..any help would be great, thanks!
