Hey everyone. New member here. Got a question concerning the Galaxie.
I was wondering if it was possible to simply drop in a pair of 6v6s in place of the standard 6L6s in the power section along with a simple re-bias on the amp to take it from 30/40 watts down to approximately 18/22 watts?
I'm seriously considering picking up a Galaxie here in the VERY near future. I'd like to avoid also having to pick up a pair of yellowjackets to power-down the power section. I STRONGLY prefer the 6v6 option to converting the power section to EL84s. Of course some of you will ask "Why doesn't he just buy a smaller amp?" Unfortunately, I play is venues of varying size, some MUCH bigger than others. I would realy like to use the same amp for all gigs.
Any suggestions or help you could give would be much appreciated. I guess if all else fails I'll have to start looking for the Z Break.
Thanks, Gramps

An Airbrake would allow you to knock the volume down a little for small clubs, and I would think anything bigger than a small/medium club would have some sort of house pa system. Or the Z28 is a great amp with 2 6v6, and for larger gigs you can mic the cab.

I suspect the Yellowjackets will totally change the tone and feel of the amp. If you like the tone of the amp I would consider the Air brake to tame the volume.

The Master Volume makes these other options superfluous. I know people swear by output tube distortion but I don't find it necessary.
My bad. I was thinking of the Evan.

The Galaxie doesn't have a master volume, and it certainly doesn't work in all amps.

Never us 6V6s where a 6L6 goes. The voltages are too high for a 6V6, bias sweep range is different and even if you can bias the OT primary tap is of the wrong impedance.

Yeah I think the max plate voltage for a 6V6 is around 350V and the Galaxie is over 400 so that is a no go!

I have actually run a pair of them in a Fender Super Reverb at 470b+ and biased at 30mA as I would 6L6 tubes just to try to blow them up but that is not the design spec and the tube impedance is NOT what is expected from a 6L6 output transformer.

not to contradict you Myles, because I'm a COMPLETE NOVICE when it comes to all this stuff, but I know people have been putting JJ 6V6s tubes into Fender Hot Rod Deluxes/ Devilles for years - the guy over at EuroTubes.com even recommends it if you want earlier break-up and power tube distortion and markets 6v6 tube kits accordingly. But those are obviously different amps.

If you are gigging in a band just drop in a Brake Lite and the Galaxie is good to go - great volume for shows. Actually to me the Galaxie doesn't seem all that loud - but maybe my hearing is just starting to go

OK, good one MS Rose, but will you blow-up a Galaxue using 6V6s?? [/font][/size][/quote] Well ... I would never do that but talk to the Doc and maybe he will bless the idea.

I guess my opinion on this is that I'd never run 6V6's where a 6L6 "should" go either...even the rugged JJ's. As Myles said, the impedances of 6V6's and 6L6's aren't the same, even if the bias pot has the range to bias it up without modding the bias circuit.
Just my .02.

the middle and care free ground here is to run a pair of 6L6WGB's in place of the GC's.
