IT. IS. FINISHED. But not without a little more drama...
The Gold Lions arrived today. First of all, I realize that this is silly but OMG they are beautiful!
I managed to get the bias set to within 1-2mV of each other, which was such a relief after all of this drama.
And then...NOTHING. No...
Hey, speak for yourself there, pal! :D
No, I haven’t really noticed any ill effects. But since this amp is new to me and I just dumped a bunch of effort into combating a related issue, I would really like to hear it with well matched tubes.
But that’s also partially why I went with the Gold...
Yup, that’s what I got (well, it was listed as .6). I am tempted to try your idea of replacing both with something more robust, but this should be fine, right?
I ordered some Gold Lion KT66’s, as long as they really are in stock like it showed on the website. More expensive, but still less...
OP checking in here. Good news and bad news...
I finally had a chance to change out the blown resistor last night. Man, that was a PITA...so much stuff to unplug and move around. I would say it went pretty well. This is what I ended up with (elevated, to hopefully deal with the heat better)...
Yup, the plastic base has come loose. Pretty sure that’s it. I freaked when I first noticed (and ordered new tubes), but it doesn’t seem as bad as I initially thought, and I have found another culprit for the bias mismatch.
Good point/question. I’m going from memory here and the tube has since been removed, but I’m fairly confident that the loose tube is on the opposite side from the blown resistor.
This amp has supposedly led a pretty tame life. That’s based on statements of the previous/original owner, but it...
Interesting idea (thanks for the suggestion!). That would make it quick and easy and also get the component floating over the PCB which might help with heat dissipation.
I may need to remove the daughter board anyway, since it’s buried in a pretty hard to access area, but I will definitely...
Thanks y’all.
The amp has the stock Marshall-branded KT66’s. They supposedly have low usage, but I just got the amp so I can’t say for sure. I initially panicked because one of them had come loose from the base, but it really doesn’t seem as bad as I initially thought. I did order some...
Howdy folks,
This is my first post in this section. I’m just hoping to get some insight from people who know more about this stuff then I do (not difficult!).
I recently purchased a VM 2266C that had been pretty lightly used and sat for most of the last 7-10 years. It’s in fantastic condition...
Well, the SV20H is finally gone. A little sad, but the right decision for me, I think.
I fired up the Vintage Modern for some final comparisons. I think the biggest difference for what is m trying to do is in the speakers. The G12C’s are great, but I just love those heritage greenbacks. Once...
Boo. Good luck/bad luck. I stumbled across this thread while searching for something a lot more general:

Aaaaaaaand…
Sheeit. I haven’t measured it yet, but I’m assuming it’s toast.
Looking at it now, the KT66...
I’m on the mofo!
I got a smokin’ deal on some “new and unused” TAD KT66-STR’s. Not sure I believe that, but at about half price I couldn’t resist. Hope I don’t regret it. :)
I just ordered some stuff from Tube Amp Doctor yesterday! Had I known this was coming, I would have added some KT-66’s...
Tried to set the bias today. As per usual in the world of old amps and solutions looking for problems, all is not as it seems…
One of the KT66’s has clearly separated from the base and is wiggling around pretty freely. I’ve heard of this happening, and hope it doesn’t become a recurring issue...
Just checking in, because…because.
Very happy with the Vintage Modern so far. Absolutely beautiful clean tones, and nice drive, too. I’ve found convincing super clean Jimi tones through early Slash tones. Seems like I can generally keep the master up to at least half on LDR, if not even more...
Well, I did it! Guy was very nice friendly, quite the talker. He is the original owner and used it in an educational context for about a year, it’s mostly sat idle since then.
Sound is cleaner and maybe a little brighter than expected. Volume is much more manageable in general, but the master...
