I was wondering what tube complement you 5F1 users are running? I'm new to playing around with tubes and from what I understand, a simple circuit like this is greatly affected by tube choice.

I find my 5F1 to be very warm, and would like to brighten it up a bit. I'll be playing a Strat through it, if that helps.

I've got a Victoria 518 - which is their repro of a 58 5F1 Champ. I'm currently running a JAN Philips 12AX7 and GE 6v6. I've also had great luck with a Mazda 6v6. I've tried a couple new production 6v6s and they are nice but, the NOS stuff really shines. Well worth it.

If you are using the stock 5Y3 rectifier tube - change to a 5v4. The amp is meant to accept it. This will tighten up your bottom a bit, and give a bit more volume and punch. It's still a compressed amp - and won't be super tight when cranked but, the 5V4 will help.

Currently, in my Victoria 5112(5F1 with a 12" speaker), I'm running a Weber Copper cap version of the 5V4, a JJ 6V6S and a NOS GE 12AU7. Stays pretty tight, but I think I do lose some volume using the 12AU7.

I also have a vicky 518, and am running a NOS JAN Phillips 12ax7, a JAN Phillips 6V6 and 5Y3. The NOS tubes are a VAST improvement over the new tubes made today, especially the pre-amp tube. I would defy anyone to hear any difference from a real champ of that era, it's that close.

I always wondered what they sounded like, I think I'll try that out. any particular brand? Thanks SB.
