Can't hurt!! Just so you know, Scott biases these amps at 65% plate dissipation. Some guys like it colder and some hotter. I have mine biased hot right now but it doesn't make a huge difference in tone. And id like to get a little more tube life, so I'm going to bring it down a little. What tube did you put in? Out of curiosity, where did you read that he biases to 65%? It was one out of fender deville, now I got some issue going on in v2, I was tapping the tubes with the volume up and v2 always was making a sound through the speaker. I keep trying different tubes and the same thing so I don't know if something is wrong with that or the amp is frying my tubes or what It is rare but it is possible that the socket has gone microphonic. Basically, that would entail a solder joint has gone bad. I'm not a tech though so that is a complete guess. I'd buy a brand new 12AX7 (or maybe a 12AT7 as mentioned) and see if that makes a difference. Below is the tube layout.

Could it be output transformer?

When I bought my bias probe, I emailed Scott and asked him what % he biased at. Elwyn... Also...I asked him (Scott) about that noise when tapping on V2....he said because it is the OD gain stage it's completely normal to hear noise from it. As long as it isn't squealing(which would indicate a microphonic tube) it's not something to be too concerned about. I tried all sorts of tubes in V2, from brand new to NOS and they all make noise. I think if you read back on this thread, it's all in here. I was having these same issues so it should all be addressed here (I believe it's this thread,anyway)

Oh well took it to an amp guy and he says that everything looks fine so I guess I just don't like it but I thought this thing sounded incredible when I put the jjs in and then it fuzzes out idk, the clean channel keeps sounds like a fuzz box, what in the world is up with this thing, very difficult to play lead on and it shouldn't be that way. has anybody else seem to have this issue

I'm thinking I may buy an attenuator, too. I was reading some old threads here about it and the Ultimate Attenuator got some good reviews by a forumite...I forget who.. Try the Webber Mass 150 or 200 bro! It's not stepped so you can get the volume exactly where you want it, and the treble compensate function is great for low level recording. I used the UA with my Super Sport for a few years and after a while I found that it sounded not a whole lot different using the master vol or the loop vol so I sold the UA . I recently set up the Super Sport on a Splawn 4x12 with Scumack speakers in a large room where i can dime the loop vol and crank up the amp a bit and it sounds like thunder

I was just figuring the attenuator would help get rid of the low volume fizziness. But if you're saying the loop volume basically does the same thing...maybe I'll just save my money!!!

When I first unboxed mine and plugged it in I didn't like it at all. Someone here, I believe Splawndude told me to set the controls with my ears and not my eyes...best advice I got. Never mind setting things to where you "think" they are supposed to be. Set it to where your ears tell you it sounds good. I have both the treble and presence completely off and the mids pretty low as well. I run a 10 band eq in the loop and tweak from there. These amps can be a bit stiff and difficult to play leads with. Give it at least a month to get used to it. It's not as forgiving as a Marshall. Also, try turning the volume up to 11:00 or noon and see if the fizz goes away. If you have the loop volume knob turn your overall volume down with that. These amps need to be pushed. I recently learned that as well. When I turn mine up---no fizz.

Well I think I've figured it out lol! I put 10 band eq in front of it and I put attenuater, loop pedal, delay, reverb, delay through the fx loop with the volume all the way up on fx volume at 50 watts into a cheap 4x12 Marshall cab and I love it, oh and I put tung sol pre amp tubes in v1 and v2 don't know if this has a lot to do with it but I think I just got to learn how to drive pedals into pedals and boosts to drive the amp

The Tung sols are great tubes. I run my MXR 10 band in the loop....you may like it there as well.

What Attenuator are you using?? I'm in the market. I'm leaning toward a Weber mass because they aren't stepped...it's got a linear volume control, which I like.

Good to hear Elwyn Like GTRJ is saying try the EQ in the loop and then boost the amp with a standard clean boost pedal. Weber MASS is good because it is not resistor based. It has an actual load coil (speaker motor) to dissipate heat and kind of replicate what a speaker's magnet coil would do. I was thinking about renaming this thread "20 Questions"
