Guitar Amp Tubes

Check out the tube store site. They have reviews of the different manufacturers (lower right on the home page).

I have not worked with the Fender, but the Peavey does not react all that much to tube choice. I think you could swap the EL84s with some JJs or EIs and have a slightly cleaner, tighter sound, but it will not be fundamentally different. Bob at Eurotubes can pick out a hot set of EL84s that will make the amp go into power tube overdrive a little bit faster, but you are talking about having the amp turned up very loud to hear it.

As for preamp tubes, you should consider an NOS tube for V1 (12AX7 or 5751, but I would shy away from a 12AU7 or 12AT7), like an RCA or a Philips, or possibly an Electro Harmonix, a European tube for V2 (JJ, EI, or Mullard or Brimar if you are feeling crazy), and a high gain, low noise Chinese or Electro Harmonix tube for V3.

www.kcanostubes.com is a good resource for these kinds of preamp tubes.

If you are fundamentally unhappy with the Classic 50 tone, sell it or trade it toward something else. You are not going to get it to sound different without drastic modification, and there are people out there who like them stock. Steve Ahola has such mods on the web, but you are looking at a virtual rebuild of the circuit.

Good luck

looks like i read too fast, i ment to say the el-84s are not a swap for the 6l6's...i always thought that's what the peavy had as well...I should pay more attention i guess.

Mrpapa why the adversion to 12au7

if you want to get into power tube saturation without having ear splitting volume try an attnuator. The Dr Z airbrake designed by ken Fisher is the most transparent i've used, a tad pricey but worth every dime

Generaly speaking the small preamp tubes make the bigger impact on sound, try rca,ge or sylvania for 12ax7 they sound good, are durable and cheaper than nos european. 12at7 and 5751 are the usual lower mu sub for 12ax7 not the 12au or 12ay. JAN phillips is the bargain 12ax7 and cost about the same as sovtec which I prefer to chinese. Having said that, smooth plate telefunken and mullard made my ampeg sound its best. I play harps and the sound was rounder harmonius and I finally got rid of this terrible glare that kept popping out on the lower highs, hi c i think it was. If the amp squeals or distorts check the power tubes first. Mullards and ge seem to be favored by a lot of guitar rollers and I'm looking for some to try. Go with what you like to hear, way to often people in the bars are treating live music like background music-that is a shame so fellow music lovers appluad, cheer whistle and show the bands some more love.
