No, they used the same OTs (and pushed the 6V6s beyond their specs).

I'm thinking about doing a tweed Super build and have an idea to throw out for perusal. The only difference between the 5e4a and 5f4 versions, as far as I can tell, is one resistor. So, I'm thinking about putting both on a SPDT switch and be able to use either 6V6s or 6L6s. Anyone see any problems w...

And yet another pops up on Reverb.

Well, about 500,000 dimes to be precise.

An amp tech friend had a sleeve of 5751s that he let me borrow. A Sylvania Gold Brand was first and the hiss was non-existent! I didn't notice any ill effects from the theoretical gain drop, was still plenty loud and the basic sound was the same. The RCA and GE 5751s didn't test as well, both a litt...

Ok, that gives me a place to poke at. I wondered if it might be the preamps; I originally had an RCA in V1 while I was working out mechanical noise issues, but switched to an Amperex (dimpled disc getter) I got in. I didn't remember it quite as hissy with the RCA, but it had been awhile.

Thanks.

Due to the search function being out of whack for the time being (results lead to empty posts, if you haven't tried recently), I need to ask a perennial question again. Finished my first Express build, and have worked out some mechanical noises, now it's sounding good, but it has a persistent hiss. ...

Why no Champ on the list? If you need it at apartment levels, that's pretty much the one that you can dime (well, actually 12 for a tweed Fender) at your volume.
Clapton, Joe Walsh, etc. can't all be wrong.

Won't your Airbrake be able to get the 5E3 down to your volume needs?

Matchless Clubmans and Chieftans are EL34 based too.

Now you see why Leo used Lupe Lopez and the other lovely ladies to assemble the guts. Their smaller fingers made it a lot easier. I had the same fun doing a 5e3 build.

What is it?

It's Lupè Lopez' signature. (She the one pictured in the Fender amp book wiring tweeds in the 50s.)

Yep.

First time seeing this thread; very nice!

Here's a little treat. Look what I found inside my '54 Deluxe 5d3...
