Got my 6AR6 --> 6L6 adapters today so I'm going to try out my Tung-Sol 6AR6 in my Mogwai SE.

OK, so, to answer my question from earlier, the 6AR6 with adapters will indeed play with the Mogwai SE. And it sounds stellar. Bigger stage, more details compared to the Tung-Sol 6L6GCs I had in it before. Just an amazing performance boost.

I paid $60 for the pair of tubes and another $40 for the adapters, compared to prices of stuff like the 6550.

Hmmm if 6ar6 work for the Mogwai they should work for the bigger Ben. Hmmm. No compatibility problems?

Just a note for any of you with a revision 2 or any model ampsandsound that is using the 9 pin input tube and prefer a lower gain input tube, I decided to try the JJ ECC802S and it has quickly become one of my favorites. JJ lists it as a "high performance 12AU7" It has longer plates and was designed to drive larger power tubes, particularly 300B. So far I've tried with Siemens/Telefunken EL34 and also MESA 6L6GC and it is great with both. Dead silent noise floor(BB rev 2 is pretty much silent anyway unless something is acting up).

Perhaps check compatibility with Justin to be sure. I guess there can always be better options but I'm pretty happy with GEC KT-88 or TT21 in the BB
I have some GEC KT66 on the way, which should be fun.

Tonight I'm trying a Mullard 10M gold pin 12AT7 that I stole from some poor guy on Ebay. He couldn't read the writing and listed it as a "TOM" instead of 10M! Thank you for your TOM tube, sir.

I don’t think so. They sound fantastic.

A question for you with amps that take the 6SL7 natively: Are there any other tubes besides the 6SL7 and it's direct equivalents that can be safely used without adapters? For example 6SN7 or 6BL7's or anything else? Thanks.

6SN7, 6F8G with adapter, 2, 6J5 with adapter. A TON of 12AU7, 12AT7, 12AX7, and numerous variations of the 12A** types (6201, 7728, 7730, CV4043, B309) with adapter from octal base to 9 pin base. I am getting some 12BH7 to try this week. A2900 is OK at least in the BB amp.

Silly question of the day. If you're looking at the amp from the front with the volume pot on the left front corner, would the left kt88 tube be the left channel, and the right be the right channel? It would make sense, but I don't want to open it up and check the wiring. Thanks! I'm identifying a tube issue and want to make sure I identify the correct tube based on the channels.
