    Many threads discussing well built amps but what do tube amps that are built like **** look like? What makes them so terrible and do they still manage to sound good despite their questionable construction?

    Well I wouldn't know, because I don't open my amps up unless for good reason.

    I don’t know if it’s the worst built but my at mars specialist wasn’t the prettiest inside. But it sounded amazing.

    I remember Fab Amps being a disaster. They were electrically unsound, and would probably kill you.

    JTM 30/60 overheating. Needed to keep a fan on her even biased cold. Tone was worth it tho

    Oh wow, forgot all about those. Some 'epic' threads on HCAF back in the day. Rob wasn't it?

    Crate V100. Had a switch mode power supply to power the tubes.

    That foldable PCB in the Peavey classic 30 is an absolute monstrosity of amp design imo.

    Love the Lee Jackson Ampeg heads, but everyone I’ve had has had catastrophic issues.

    Built, as in the build quality? I've honestly never been impressed with the majority of offshore tube amps that I've seen. Many of them don't get the same love/care as a lot of boutique amps or like what Mesa and other higher end builders do. In fact, any of the 'big name' tube amps these days seem to really have only bedroom/practice amp build quality. Even the new Marshall's that came out recently have a pretty cheap build to them and they're made in England so it almost doesn't even matter. You pretty much have to look else where to get a well built amp IMO.

    As far as the sound quality.. well thats all in the circuitry, tubes, output transformer, etc. You can still build a really great sounding amp with **** components, it just may not hold up over many years like one would hope.

    Yep.
    But! If the production issues are taken care of, they sound awesome!!!


    Addendum;
    the components aren’t crappy, which is a plus. It was a wiring issue.

    Peavey classic 30. The early ones sound great and i wouldn't let the build quality keep me from using one as i have in the past. But that triple circuit board design with about a 100 inch long pieces of solid wire completing the connections from each board to the next is one of the worse designs i ever saw for reliability. I had 3 of em and 2 of the 3 went down at gigs due to one of the wires fracturing due to the vibration during transport.

    An amp doesn't have to be real well built if it's just sitting at home and these days most of them do.

    My Marshall 3203 Artist went through two power transformers. The second time the transformer went out it was with fire and black smoke.

    I don't know about being worst built, but I was never fond of the Marshall JCM2000 series. The circuitry looks more complicated than the new DSL series and the power tube sockets are mounted to the main circuit board.

    It's not the worst but certainly not ideal. I had a DSL50 back in the day and it had the dreaded bias drift issue and every time I went to change tubes I could feel the boards flex as I pressed the tubes in.

    The JCM2000 DSL401 combo was the real stinker of that range because it would overheat and develop cold solder joints.
