Tube preference

Has anyone tried a different set or value of tubes in a peavey classic 50? If so what were your results.

Don't know a great deal about Peaveys in general,but from memory the classic 50 runs a quad of el-84's no? If thats the case, without resorting to rather major mods, your only (decent) power tube option is el-84, just different brand types.

My 25W Peavey Bravo uses two EL84 power tubes, and I recently bought new Groovetube EL84-S tubes to replace the ones which were installed by a repairman. They come in 3 "ratings": blue, white, and red, and apparently this order is from most to least distortion with reds giving the most clean power/headroom according to the GT packaging. I'm not sure the mid-range whites I chose were appropriate, perhaps the reds would have given me the clean channel headroom I was going for.

This site has a huge variety of apparently reasonably priced (haven't bought from them) tubes and pretty in depth descriptions of their attributes:

So apparently there are variations among essentially interchangeable tubes that some ears can perceive. I wish I could try them all and see what's hype and what's real. The pre-amp tubes also are available in quite a variety of gain levels: http://thetubestore.com/gainfactor.html
