If all your colors match this than I would guess Orange and Blue. Use an ohm meter and check resistance to verify..... Orange and blue would be the highest reading if below is correct. followed by Orange and yellow and then Orange and violet or green.

I've never seen an original but I did built a clone. You've already heard all the descriptions so I agree..... It's a different kind of amp It requires a more aware player to know how far to dial it back. Overall I found the build easier than average.........5 knobs 5 tubes no choke no...

Im confused, it was just bad tubes?

:woot:

seems fine to me

I've done this too, so i know it's a good feeling when you realize it.

The Tube amp Expander is another option that works really well, I know a lot of other guys here use it as well.

22k linear is my guess......I would try and get a reading off it when you pull it out to confirm.

Not sure I could live with a 10"

7.3 would be acceptable if you use KT66, but as mentioned above not very good for el-34s

Sourmash to the rescue...........again

Pete is right about the size "honking big" that is the one thing that sucks about the old ones they take up a lot of bench space. Getting something smaller and modern would be nice. Probably why so many old ones are available.

I wouldn't cover serial numbers, it contains no personal information, and proves the amp is what it is. If it is covered I would suspect foul play.

Yes just cut and insulate unused wires. I leave the unused secondaries long and insulate incase I want to change voltage later. But not necessary if you aren't planning on changing taps.

nice looking amp

Just to update I did get the sourmash cabinet for this. Those guys must be busy because every time I order a head cabinet it takes longer and longer, 5 weeks for this one. I don't mind the wait I'm never in a hurry. Work has gone into pre covid status for me (work all the time) so time is...

Sounds like it's time to change that. Nice thing about working on tube amps is you don't need a hi-tech expensive scope. Them old ones work fine, usually around $100 or less. It's nothing more than a glorified volt meter so it won't take you long to get the hang of it, and if you do blow it up...

sounds like oscillation to me....Sucking all the power from the amp. Whats it look like on the scope?

I agree
