Thanks, everyone. Much appreciated. Goldeneraguy, a pair of 845B tubes is in the works already.
6SN7 tubes
Hello!
Come looking for a little help. I have a Mastersound Compact 845 amplifier, and I'd like to put some NOS tubes in it to replace the stock Electro Harmonix. Not the power tubes, just the driver and pre-driver tubes. Kinda stuck with Shuguang for the power tubes...
Anyways, the pre-driver tubes are 12AU7/ECC82's, and the driver tubes are 6SN7's. Problem is, the pre-driver stock tubes are labelled 12AU7A...the driver tubes are labelled 6SN7GTB.
I have a matched pair of NOS Telefunken ECC82/12AU7's- minus the "A" designation at the end. Can I drop these in, or is it a question for the maufacturer? Also, I'm hunting for some NOS 6SN7's- does it matter if they're straight 6SN7's, 6SN7GTA or GTB?
What's the difference with these minute designations at the end of the tube name? Am I overcomplicating things here?
Thanks in advance for any advice!
