Re: White noise.

Voltages are higher, gain is higher. The amp is more sensitive, responsive, and dynamic. What you report should not be unexpected.

How is it with the pedals NOT in the loop?

You may have to adjust a few parameters to compensate for the effects of freshening the amp.

Re: Studio. 22 speaker upgrade battle

I've found very good condition lightly used EVs for a hundred bucks and that's pretty cheap. It's in your budget if you decide to wait and save just a little longer.

EVM-12L. I've done it and it sounds incredible.

Re: Using a 12at7 in place of 12ax7 in dual rectifier

At a certain amount of gain the amp will start sounding fizzy. A lower gain tube will simply allow you to turn the gain knob farther before you reach that fizzy spot. I've done some tube swap experiments and have certainly heard subtle variations in the overall sound of the amp in addition to the ga...

Re: New Fender Amps..

I think Fender made a commendable effort with the reissues they've put out lately but in my opinion they miss the mark. I would suggest that in many cases you can get a clean original example for less than the cost of a new "reissue" that doesn't quite capture the tone of the original. Have that ori...

Re: MARK III BLACK STRIPE SNAP CRACKLE POPPING

I have a topic on this issue. Guys, if your amp hasn't been recapped and it's 20 years old or more, it's due. Caps can fail at any time and at 20 years old they're past their designed expected lifespan. https://forum.grailtone.com/viewtopic.php?f=3&t=84878 Red plating tubes indicates absent or insuf...

Re: Solo Head 50 low output

Can you safely check the plate voltages on all the tubes and screen voltages on the power tubes?

That'd give some good data to think about.

This is why replacing capacitors is NOT optional!

This amp came into my possession today for a song...or more like a couple of licks. Cheap enough, at any rate. It's a Fender Super Twin. 180 watts in a Twin sized package. Never known for having a good overdrive tone, but notorious for its ability to push out that clean Fender tone at absurd volume ...

Re: Replacing Power Tubes in a solo 150w head

Matching rectifier tubes is mostly a matter of ensuring that they all deliver a fair share of the load. You probably don't have to worry about it much as there's no bias consideration in play with the rectifier tubes. At worst, you'll have some that just don't deliver as much current as others which...

Re: Mark III NOS Tube Suggestions

NOS? That's going to cost you. People are selling pairs and quartets of STR 387s and STR 415s on ebay, allegedly NOS. How well matched are they? Who knows? Are they really NOS or just not used enough that you can tell by looking? You won't know until you try them. You can still get STR 415s from Mes...

Re: Some tube history about Mesa's 6L6GC STR454

The 454 was Mesa's branded version of the very high quality Svetlana 6L6GC. Svetlana became "Winged C" brand became SED. The factory closed in 2014. Unfortunately. As I understand it, the Svetlana 6L6GC was designed to follow in the footsteps of the almighty Sylvania/Philips/ECG STR415. These tubes ...

Re: Mark III no distortion channel 3

Yeah, on my amp at least, volume 1 pull bright has so little effect that I actually thought it doesn't work at all unless in the lead channel.

It's more apparent in the lead channel but it's subtle at best.

Re: Mark III no distortion channel 3

That video doesn't tell us anything other than the lead isn't working. For all that video tells me, it might even be that the switch on the lead drive pot itself could be the faulty part. You turned the lead master up, with lead engaged. But you didn't turn the lead master up with the lead NOT engag...

Re: New tubes, where to place them?

Just mirror image the pairs. Doesn't matter which pair is inside and which pair is outside. I have a friend who's been using yellowjackets on one of his amps, a Kendrick Black Gold something. 35 or 15, I don't remember which. Anyway, it makes those EL84s run stupid hot.
