Default rectifier tube recommendation for champ clone

I'm adding a choke to my STF champ clone (has a way oversized output transformer and a bit extra filter capcitance) and later may add a second 6V6.

It's got a 5Y3 right now. I might even put a solid state bridge on a tube base... But what I'd really like is a better rectifier tube with a bit more voltage (less voltage drop) and more current capability, assuming such a thing exists.

If you want less droop, a SS rectifier is probably the way to go.

I know it's not as 'cool' as a tube, but may be the ideal solution.

How about a 5V4GA? What size choke are you getting, and are you using a CLC after the rectifier tube?

Google GZ34/5AR4 swap for 5Y3.

I'm not exactly after less sag (or I would beef up the power transformer and go to solid-state rectifiers), just less loss and a bit more current at the rectifier, so that I can add better filtering and a bit more current storage.

STI makes a "super-duper" (my words...they call it Deluxe or a SuperCharged but that has other fender connotations of push/pull, which it's not) kit similar to what my entry-level kit is evolving into (two parallel 6V6 single-ended), except mine will have an even bigger output transformer and theirs has two rectifier tubes. I'm trying to get away with the same power transformer initially, so it will have a LOT of "sag" when I push it hard. But I'm adding chokes and caps, so it might be pleasantly clean and even 'chimey' at lower volumes.

yep, that was the idea, still a smallish cap at the rectifier, then a larger one after the choke. So hopefully no in-rush at start-up. I'll model it first, of course.

Sovtek brand "5y3" provides about 20-60 more volts than non-Sovtek brands.
