About selling or the issue.
I am 100% serious about the tubes. You have a lot of homework to do and run the risk of killing yourself if you DIY your repairs, or get to lug it to a tech for $ 95 an hour. You have to buy tubes at $ 20 each. And why exactly? Because it is supposed to sound warmer than a new breed of SS amps, which really only happens at higher volumes, which I do not play at.
Everyone needs to experience tubes during their playing lifespan so they know what it has to offer. For my home playing needs, it is beyond unnecessary. I do not enjoy amp repairs like I do guitar repairs and mods. I am moving to the next phase of my life - enjoying my time by playing instead of fixing at the risk of electrocution.
I'm there with you, my friend.
I have played a lot of vintage amps - including JTM/JVM Marshalls, Vox, Fender, etc - and honestly, I cannot hear a difference between them and the new amps. The only difference - like you said - is enjoying playing. I have a JVM-410C that I never use. It's been up at Mom's for 20 years or so. I liked it, but I would sometimes get a bad tube from transport and try to swap tubes just before a show. My JTM30 Combo would overheat and shut down.
What amp do I see more in recording studios (both as house amp and as a rental) than any other??? Roland JC-120 hands down. Wonder why???
Guys laughed when we pulled up to Wasteland Weekend with a Line 6 Spider II HD-75 and Jackson 4X12's. After a lot of tube amps crapped out in the 100°+ weather and direct sunlight, they didn't laugh so hard. I loaned that rig to two different bands when their tub amps went down.
I know, "Line 6 sucks, it's made in China" and all that, but it worked and it held up for a 45 minute set in blowing sand and intense heat and no broken tubes from being banged around.
My owned-since-brand-new 1997 Marshall Valvestate seems to be an incrdibly solid amp. I replaced the original 1997 tube last year and didn't need to, I just figured it was a good idea. Heavy, Noisy, but never gave me any trouble. It spent 2 years on loan to a musical friend who toured Japan with it too, so I know it's been abused.
I have probably spent more time fiddling with my DSL40C than I have playing through it. I
I have bought 4 or 5 completely different sets of tubes, matched this, biased that, 5751/ECC83MG, ECC83S, JJ EC823, 7025 WA, KT-88, EL-34, a vinatge (expensive) set of Ken-Rad 12AX7's from the 1950's, a custom $149.00 WGS 50 Watt Reaper 55Hz, Special speaker cables, $220.00 for a Weber Attentuator, and it still doesn't blow me away.
My Marshall 2203 was a problem child too. All the headaches of tubes and not even a reverb feature.
I think I am an average guitarist, but I think my recorded tone - and always near-perfect tuning on a recording - are above average. If you listen to some of my tracsk, you will hear the same amplifier over and over again - Blackstar ID-Core 100watt Solid State.
Why???
It cost 4349 brand new, has a tone of built-in effects, has spatial (panning) delay feature, has a direct out and headphone jack, is dead quiet and sound good on tape. It causes me zero issues.
I don't mind working, swapping tubes, etc., but to be doing this much work - and still not having a tone I really feel confident with, what the hell am I doing this for???
To be able to say "I have a Tube Marshall?"
Seriously rethinking my main amplifier needs here....
To be totally honest....if a good cleaning will get rid of that buzzy/crackly quality on my VS265, it might just be the best amp I have for live work. British made, 65 watts RMS, line out to drive two cabinets, effects loop, easy to use footswitch (brand new and still in the original box) Eminence speakers.
Lot's to consider here.....
