I have a 100w JMP with new EH EL34s in the power section. i really like the real warm blues tone like gary moore but i also like alot of Van Halen and that Hard rock stuff like GNR and even 70s calssic stuff but all of it real warm and creamy, i want to Know what sort of Pre amp tubes would be good with the power valves i already have.
Thanks for helpin me out.

A set of EH/JJ Tesla/Tung Sol/Mullard NOS etc 12AX7s should get you in the zone.
All the guitarists you mentioned get their tone from driving the power tubes hard and you'll have to do the same. It's mostly power tube distortion you're hearing. A good attenuator is the best job for this as it lets you drive the output tubes with making your ears blead. Roll back the preamp gain and hit the power amp hard and
This is the opposite of high gain metal players who tend to get their tone from the preamp section.

My pick for my 100 watters:

V1: Since V1 has the most effect in the preamp section I want the most low noise tube with the most amount of gain for a reasonable price. ECC83S and TungSol 12AX7 apply on these criteria. Although TungSol 12AX7 has a tad less gain compared to JJ ECC83S it is a more musical tube and more pronounced in bass, mids and highs. For that the TungSol 12AX7 is my favorite for V1.

V2: mainly tone shaping; I have JJ ECC83S in my JMP and a old Mullard ECC83 in my SLP. Both tubes tame some of the highs (i work with M25 Greenbacks).

V3: Phase Inverter; As of today i can confirm the hype about balanced phase inverters, at least this is the case with my Marshalls. I don`t know about other amps. Today i`ve put in Philips NOS JAN GE 5751 in both amps. They do not only make the tone tighter (bass in particular) but also sustaining notes sound lots more musical compared to other non-balanced tubes such as TungSol 12AX7, Marshall ECC83 (white label= chinese), Mullard ECC83, JJ ECC83S and JJ AT7 i`ve experimented with.

Thanks guys i think il try the jj ECC83 s ive heard alot of hype about them thanks for the help.

how about the TSL 100 100watts it has 4 preamp tubes what does the V3 do? cuz the V4 is the phase inverter.

Don`t pin me on on this but if i recall well i thought one part of V3 (in a 4 stage preampsection) is assigned to reverb/tremolo/vibrato (maybe even line out and/or fx-loops) and one part adds a tad gain to the incoming signal.
