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.
Guitar Amp Tubes
I have two guitar amps and I am wondering what if I changed the stock tubes. Peavey 4-10" classic (3) 12AX7s and (4) EL84s and a Fender Blues Deville (3) 12AX7s and (2) 6L6s. I have no experience with these tubes in my stereo rig so I need some advice. What tubes would your try and what should I replace first the 12AX7s or the others (EL84/6L6)?
Thanks
