Try a 12AT7 Billy said. It'll be fun, he said.

Remembered I have a couple/few old Tung Sol 12AT7 tubes I got from a thrift store bulk find. I assume they're from the 60s but I haven't researched them.

Anyway, per Billy's advice I decided to toss one in the PI slot of the DSL I've been working on. After replacing a few blown resistors I changed the PI tube at the same time.

Turn it on, and .... whisper quiet volume almost like it was when I bought it (cheap DOA project).

Got pissed thinking I blew another heater resistor, but it ended up just being a dead preamp tube :lol:

Tossed in the Mullard that came with it, and all is good. Then said screw it and installed a choke that I found for $8 on Reverb.

I'm going to try very hard to not flip this amp. It just oozes solid rock tone. Oddly enough I'm liking this with Mesa V30s.

:lol: :lol:

To be fair, the difference with 12AT7 is somewhat subtle. Unless the tube is dead. Then the difference is pretty big :lol:


And yeah I run my DSL with V30s. It's a good match.
