Thanks for the feedback, but there is so much to try going forward. That was the amp with Chris's PT and the MM OT which I built along side Ben's amp back in 2011. I'm kind of hitting a wall with this amp, I think it might be the MM iron making things a bit too modern sounding. When I get things up and running again I want to work with my other NOS amp with the Marstran irons, the tone was initially a little more woody, but I was having noise problems.

I don't know if you can tell from the clip, but the tones is sweet from top to bottom. Once you introduce an MXR 6B that goes away, so I still can't bring myself to plop some sort of boost after the guitar. The plates were down to 354 with the bias at 2.50 (1.64 was the correct formulated target for biasing without a 1ohm resistor), still, this variac thing is not changing things all that much. Try this: crank your amp and jam away, reach over and turn it off, but continue to play. There is a point where the tone is quite beautiful as the sound fades away. It is articulate yet saggy, crispy, fizzly and warm, that is what I thought the variac should be emulating, but it does not at 90V. Tubes be dammed, next time I'm going to drop the variac even more and see if I can recreate that phenomena.
Based on that discussion in the other part in the forum, I lowered my voltage from about 95v down to 70. It definitely sqished things but a bit too much and I brought it back up to about 80 and that seems to be a bit of a sweet spot....right now.

At 70, what are your heaters showing?

Curse you, I just put it back in the cabinet. I brought it back up to 80. I will check.

I am really digging how it sounds. It also cleans up nicely bringing down the volume and the guitar volume.

I can nearly nail this type of tone switching between a MM 1400 and 1300 and the volume pot.

Been laid up for many months without a knee in my leg, so to keep from going crazy, I have been building away. Here is the latest build which is a kind of tribute to Mark with my own spin. The clip is useless but it was the best I could muster in my condition. Oh, I get a new knee tomorrow so once again I'll be on the wings of opioids....see you all next year. :stars:

That's one of Chris's 132's that I had in another amp. The heftier OT's are a great match with the 2203/LarMar setup. I've been playing musical OT's lately. The dark brown board looks great with 1w Pihers.

Yes nice clean build.

Good luck tomorrow ask the 'carpenter' to wash his hands first this time :wink: (says the 'plumber').

Oh and next time ask first and I will dig out some smaller Piher resistors for you!

:lol: I'm in the South now, they'll flush out the wound with Bourbon before sewing me back up, then good to go!
I just wanted to use up those big pihers, but I do have a complete 1/5w set for my jtm 45/100 waiting in the wings, thank you for offering, I still might take you up on it after a while.

You have a Dom block-end chassis, right? PLEASE start a separate step-by step thread on the 45/100 when the time comes, can't wait for that one. I will have to live vicariously through you since I can't afford one of these right now, but I'll bet you end up building my dream amp!

The dark brown board and Pihers on this build hints at a 10,000 or a 45/100... :drool:

Thanks for encouragement! Those are EH 6ca7's and I think a grey plate sylvania for V1.
