MKV power tube results

[magh8]

I ordered a 2 quads of tubes for the amp and tried them out today.both JJ e34l and kt77..

so far i like both the JJ e34l and stock mesa 6l6gc better than the JJ kt77.

the KT 77 just seemed to scoop the crap out of the tone and make the amp overly boxy sounding
now for the e34L.that's were it is at gave the amp a nice snarl in the mids and kinda retained the thump of the 6l6gc.nothing some tweaks of the EQ shouldn't fix.

so i am going to try the kt77's in my fja modded windsor they may do well in that amp.after thinking about it i should have not bothered with the kt77.I had them in my splawn nitro and didn't care for them and prefered the E34L and sovtek kt88 to them.

how does this whole "fixed bias" thing fit in when your thowing non mesa tubes in the mix?

Ive never been a fan of mesa tubes, and I like JJ tubes the best, but I am apprehensive about putting non mesa tubes in there. Would this throw the bias off? Or does it not make much difference?

I would really like to put some high gain JJs in there with either thier 6L6's or those EL 34L's. They sound really neat.

you just tell a dealer that knows what they are doing what amp the tubes are for and they match them accordingly...

so if you order from dougstubes or eurotubes you'll be okay.I wouldn't just go buy tubes off the shelf at a GC and throw them in.

as far as comparing the stock 6l6gc's and the e35l's i like the amp either way...so far kt77's wtl

Aren't those EL34L's the *****? I have a pair in my Mark IV and love the crap out of them. Thats interesting about the KT77's. They are advertised as sounding EL34-ish with a huge bottom end.

i dont think they sound like an el34 at all.kt77's do have a huge bottom end and a nice top end sizzle but they lack the midrange bite that an el34 has.they are just a drop in replacement to an el34.

so this is the second amp i have had these tubes in and still don't like them.the kt77 also gives the V a stiffer feel did the same to my old nitro.

great to know, magh8. i was on the fence about the kt77s, but from what you said, i'm just going with the tung-sol el34b's. cheers!
