So I tried a Tung sol reisue 12ax7 in V1 in my c+

[cremona]

I absolutly hated it

It suddenly sounded muddy and fuzzy , with total lose of focus and diffinition,everything i love about my amp whent away, i tried it every different V possition and all the time MY GE jan or stock mesa sounded better much better.

I have read all the possitiv things about it , but its going no where nere my amp again.

Eny one else experinced this with the tung sol and a IIc+ , dos the tung sol need burn in time ?

Can't speak to the re-issues, but I love the vintage ones in my C+ and Mark IV.

the new tungsol and the mullards are just sovteks that have been re-labeled. if you want sovtek, look at the LPS or WC versions - much better sounding

Hi

Im sure that the NOS versions of this tube is great , but this on was way to fuzzy in my amp.

havever i could tell that the tube produced a lot of gain and was very warm, combined and in a amp that is a bit to tight I could imagin it would be helpful.( the mark V guys seem to love this tube)

Actually i have orderd a batch of NOS EI tubes, but i still looking for a tube for the P1(V5) and i have heard that Doug`s tubes specificely recormends the Sovtek LPS for that possition, so might pull the tricker on those.

It may like the MKV and not so much with the C+. But according to the 'mesa propaganda' the ciruit is the same... :lol: Then again it may just be your ear does not like a sound mine does? I only have the MKV, not the real C+ The Tung Sols gave it more heat in a good way for me.

The V i tried surthenly diddent sound like my simul c+.

Mesa boogie have alwasy had a rather agressiv promotion hype going on , and it is also quit obvious that the V dossent have 83 c+ circuit board , and mains transformer in it, i think the have tried to mimic the c+ voicing, but the org c+ sound comes from a combination of the hole amp.

But it did sound awesome, and better then mk4, in its own right just as good as c+, but to my ears not as organic and diddent have the same respons feeling .

I had the same experianece in my mark IV, which really surprised me because in my recto it sounded great.

Yeah I had a very similar experience. My C+ was filthy when I found it and maybe there was a dry or dirty socket, maybe I didn't know how to tweak the amp but it sounded like a cheap BUZZ SAW! Regardless I bought it on the spot and figured I'd make it good.

I spent some time tweaking and with everything pull-able pulled it sounded better but by that stage I had already ordered a set of Sovtek 12AX7 WXTs and dropped them into the C+ as fast as I could - much better. So I don't know if it was the new tubes, tweaking or just by mucking around I might have accidentally cleaned it all up?

As for the Tung Sol's I found in the C+, I had purchased a new Triaxis at that time so I dropped those tubes into there, they sounded good and just like the tubes Mesa shipped with.

Interestingly the C+ came with a set of Mesa "Made in USA" STR415's I believe they're Sylvania's? At any rate for an experiment I dropped those tubes into my Dual Recto (just two of them for half-power) - very very nice!

Amazingly the C+ sounds pretty well the same with and without those glorious STR415's, probably because I'm mainly hearing preamp dominated tones (makes sense I never get to crank it). So if i can't pick the difference why not put those tubes away, just in case I ever record and I use standard issue 420s (Chinese I think?).

I was also very also very suprised because the rumor goes that eny tube is better then stock mesa, but the c+ sounded broken with the tung sol IMO.

I have now gotten some EI pre tubes, and a sowtek WXT for the phase inverter and it soundes absolutly awsome, i also sounded amazing before with the stock mesa tubes .

I think that the C+ is very responsiv to preamp tubes, good or bad

I had the same experianece in my mark IV, which really surprised me because in my recto it sounded great.

The Russians respond differently in cathode follower circuits like the Recto.

My rule is no Russian pre's, ever in the C+. I would rather use a JJ ECC83 if I had to.

My fav's:

NOS-

RFT ECC83- All positions
Amperex- All positions
Mullard- If you have the coin, for all positions
Ei- Mid 80's grey plate- All positions-V1, V3 and V4 may not live too long though. Penta Labs version NOS may be available.

Current Production:

Ruby/Shuguang/Penta 12AX7C5 HG+ All positions
GT- 12AX7M V1 and V5- If you can get them- Discontinued, but Penta Labs has a version
JJ ECC83- If you really have to. Good Gain, more compressed and smoothes out the lead channel. V1, V3 and V4.
Ruby/Shuguang/Penta- 7025SS if you can get them-V3 and V4-Copy of the 80's Silver Special
