How good is this custom tube amp board & parts?

Question

M i getting good things

Answer 1

It's most likely junk. First - the silkscreening is misspelled on the board (hight voltage vs. high voltage) which tells me this came from some non-English speaking place - probably China. Secondly, the wiring, while point-to-point, looks to me to be very poorly done - a rat's nest. If you spent $15 it might be a good project, if you spent $250 you got ripped-off. A couple points about your post 1) using "text talk " - M i ...blah is lame and actually against the Yahoo terms of service. 2) Your photo barely shows anything and 3) You didn't post how much you paid. So you're lucky anyone is answering you at all. Next time provide more info. PS - this looks like a pure tube amp to me - I'm not seeing anything that resembles "transistors". That said there's nothing wrong with a good-quality solid-state amp. You can get a lot more amp for the same money if you lose the "it's gotta be tubes" mindset. Tube amps *can* sound good - if you spend serious money and are willing to put up with the hassles of tubes - like having to replace tubes on a fairly regular basis, which gets expensive. Tube amps are also heavier and more fragile. Great if you have a bunch of roadies to carry it around - not so great if you're by yourself. Solid-state amps can have a good distortion channel these days, and they can also be a decent platform for pedals. Just sayin'. I played probably 2500 gigs with a guy who used a little Peavey Bandit that he paid $150 for used - less than a set of power tubes for my tube amp.

Answer 2

There are no transistors showing in your photo. That doesn't necessarily mean the amp doesn't have any. They could be mounted elsewhere. For instance, in my Peavey Session 400 all-solid state amp, the transistors are mounted to the rear of the chassis, presumably for ventilation. Having said that, everything in your photo is consistent with what I've seen in all-tube amps with point-to-point wiring.



More info is needed if you want to be absolutely certain. Do you have a schematic?



UPDATE: Yes, I followed the link to the full view (which is much lower resolution) and still do not see any transistors. The only component I can't positively identify as a resistor or capacitor is that small blue square. It has a cable connected to the front panel on the far left (opposite end from the toggle switch). What is that control/input? Ultimately, it doesn't matter if the amp sounds good.



Let me stress this point: there are crappy sounding tube amps, and good sounding solid state amps. Just because some of the greatest sounding amps (in my opinion) are all-tube, it doesn't mean that *all* tube amps are the best. Believe me...I grew up back when all amps had tubes, and there were some pretty bad ones. Everything in your photo leads me to believe that the amp is all-tube, but that doesn't mean squat unless you actually like the tone of the amp. And conversely, if you like the tone, who cares whether it's coming from tubes or transistors?

Answer 3

Yeah, about all this from an electronics stand point, I've looked at both pictures and see NOTHING that says 'TUBE' to me at all. The only things I see that might resemble tubes are the round, white ceramic objects and the smaller yellow plastic clad objects and, from what I see here, I couldn't swear in a court of law that one, single tube exists. What view am I missing? You tell me...





Also, this doesn't begin to look like a high voltage section that would reliably power tube type circuitry. Nor would I say it screams 'high quality' as much as "making a ridiculous profit". Just my opinion.



The link is to Wiki-pedia article on vacuum tubes, "tubes", and gives fair pictures off a LOT of different types. I'm not saying it doesn't have any, but I can't tell for certain from the photographs.

Good luck and I hope this will help!

Answer 4

here is a full view .do you think its gain channel have solid state transistor or its full tube path
