Apologies if this seems like a silly question. I own a MESA Rect-o-verb 50 Single Rectifier Combo amp. I have been playing with the settings trying to dial in some tones. I don't know if there's a tube issue or if its just the way tubes work in an amp. But, if I have the amp on the clean...

Hello friends! I come in search of much needed advice today :) I have an EVH 5150 iii 2x12 combo amp that started getting noisy and eventually I realized it needed new tubes. So at the advice of a friend, I went with a complete set of 7 JJ 12AX7s (I left the 6L6s alone) Well good news is...

Hi everyone. Hoping to get a bit of advice on my amp head, which started humming a few days ago. I'll try and give as much detail as possible to help diagnose. - It can be heard slightly when on standby then loudly through the cabinet when standby switched off - Volume controls make no...

Last week my power tubes were crapping out in my HT40. I switched the two TAD EL34-STRs for JJ E34Ls. The tone is fantastic - tighter lows, improved balance in the cleans, and smoother distortion with more sustain. So now I'm thinking about changing out the two ECC83 pre-amp tubes as well...

Hey Guys, Just got a H&k Tubemesiter and i really like it, i play it though my Jet city 4x12 cab and i find it pretty fizzy at high gain on the dirty channel. Im looking at buying new tubes and would like to know your experiences of different brands of tubes that you have used in your...

Just wondering if anyone has any experience with the Thermion. I bought one from a guy almost new old stock. The clean channel sounds absolutely incredible, the dirty channel....not so hot, even with the gain full bore. I was wondering if anyone can recommend any tubes or mods to me. I want to...

So for those interested in sinking big money chasing tone on their amps (a frequent discussion on the Mesa boards) I decided to make this video while my fiance was away at work! 8) It's a quick comparison of the Sylvania 6L6GC (STR-387), Ruby 6L6GC MSTR, and Mesa 5881. It might surprise some...

a bit ago my peavy 5150 gave out and stopped working, turned on the power light doesnt come on, i replaced my 2x main tubes but nothing. should i replace my 5x pre amp tubes or is it something with power supply or power chord maybe? any help would be good before i spend $50-60 that may not fix it

I have an ADA MP-1 preamp for sale. The unit is in excellent condition and sounds great. I'm looking to get around $250 for the unit, pay pal and shipping included. CONUS only.

Hi, I use a fender protube 60w (all tube) and I have a Marshall valvestate on the corner on the room (I never use it lol ). This valvestate amp have a tube preamp with a gorgeous tube distortion (the amp section is solid state, so it sucks). I just want to use the preamp section of this amp...

So I am getting a Carvin X100B probably sometime next week. It is used so I want to change the tubes. I am a tube noob since this will be my first tubed amplifier. I want to get some recommendations for EL34 tubes. I was looking at these: Electro Harmonix EL34 Groove Tubes Gold GT-EL34 Sovtek...

I've been working on getting a new subsection for "Replacement Tubes" in the comparison shopping section up. Finally got the first couple done (thanks, Alan!) so you guys can help add some new products and reviews! It's under the "Guitar Amplifiers" section. I figured there are plenty of new...

A while ago I have been thinking about my current setup: a Laney LC50-II, a Digitech RP500 for effects, and two Ibby guitars, and what I could do to improve my sound. I was thinking of doing a speaker swap or a retweaking of the RP, but when I got to thinking about changing out tubes, a thought...

i own a mesa 5:25 combo, very good amp, not exactly the sound i'm looking for, but i'm not getting another amp for a long time so i use it. anyway, for a long time, can't remember when, it's had this strange kind of ringing noise that happens when you play a loud note, like on the burn channel...

Has anyone had a chance to try the re-issued Mullards? I have a couple of 12ax7's coming, and at about $15 each compared to $50-$110 for NOS, who knows, might get lucky. I also use EL34's too so any info or opinions would be welcome.

Never used. Sold my JCM800 before I even got a chance to try them. New in the box. Bought from Doug's Tubes. pics at: http://s195.photobucket.com/albums/z48/finstah/for%20sale/Groove%20Tubes/
