Hey guys, just got done putting in new preamp and power tubes. However, I am confused about what preamp tubes control what. I would imagine it's even more confusing on my Triamp considering I have 9 preamp tubes and 4 power tubes.
I thought the spacing of the tubes was weird. I have 8 preamp tubes in the front (the rightmost one covered by this metal piece) and one preamp tube in the back along with the 4 power tubes. Is there any rhyme or reason to this?
Besides that, I did replace every tube except for that metal piece enclosed one (it was a H&K 12AX7 that showed no damaged). I replaced 8 Ruby Tube ECC83S and 4 EH EL34s. The JJs and the Svetlana Winged C EL34s really make the difference Sparkling cleans, no muddiness at all, less hum, tighter overall sound, better gain... finally sounds like the Triamp Mk II I played at Guitar Center (that made me fall in love with the Triamp in the first place). All in all, I think I'll be sticking with these tubes for a while. Unfortunately, there is no trimmer pot on my amp so I have a fixed bias. Need to get that looked at this summer. However, without biasing anything, my matched EL34s sound great
