    Vintage Modern 2266C - blown bias resistor

    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...

    Vintage Modern 2266C - blown bias resistor

    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...

    Vintage Modern 2266C - blown bias resistor

    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...

    Vintage Modern 2266C - blown bias resistor

    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)...

    Vintage Modern 2266C - blown bias resistor

    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.

    Vintage Modern 2266C - blown bias resistor

    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...

    Vintage Modern 2266C - blown bias resistor

    I *think* the tube is okay. Apparently this is somewhat common with KT66s. I’ve seen several mentions of people basically gluing them back together.

    Vintage Modern 2266C - blown bias resistor

    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...

    Vintage Modern 2266C - blown bias resistor

    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...

    Vintage Modern 2266C - blown bias resistor

    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...

    First Marshall for a Fender/Vox guy: SV20 vs Vintage Modern/2266

    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...

    In happier news, at least I have a working pilot light: ¯\_(ツ)_/¯

    First Marshall for a Fender/Vox guy: SV20 vs Vintage Modern/2266

    Boo. Good luck/bad luck. I stumbled across this thread while searching for something a lot more general: https://www.marshallforum.com/threads/vm-2266c-asymmetrical-bias-problem.59289/ Aaaaaaaand… Sheeit. I haven’t measured it yet, but I’m assuming it’s toast. Looking at it now, the KT66...

    First Marshall for a Fender/Vox guy: SV20 vs Vintage Modern/2266

    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...

    First Marshall for a Fender/Vox guy: SV20 vs Vintage Modern/2266

    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...

    First Marshall for a Fender/Vox guy: SV20 vs Vintage Modern/2266

    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...

    First Marshall for a Fender/Vox guy: SV20 vs Vintage Modern/2266

    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...

    Looks practically new! I am excite.

    First Marshall for a Fender/Vox guy: SV20 vs Vintage Modern/2266

    Me too! But I’m not going to drive 3 1/2 hours each way and not buy it unless it catches on fire or is even louder than the SV20. :)

    First Marshall for a Fender/Vox guy: SV20 vs Vintage Modern/2266

    Road trip planned for Monday afternoon. :D Hope all goes well! What a long, strange trip it’s been.
