Just because you mentioned it have you ever, played or owned a classic Pignose amp?Me too. I've had quite a few PCB amps, including tube amps, with some of them having the tube sockets mounted to the PCB itself, with zero failures to report (especially within 2 years), while I owned these amps, anyway.
Possibly the first one I remember getting was a Peavey Delta Blues in '95, with the tube sockets mounted to the PCB. I put a ton of hours on that amp, and had it until '05 or so, when I gave it to a friend. AFAIK, he still has it, and it's working fine. So I got 10 years with it and no failures, and he's now gotten an additional 20 years (assuming he's still using it).
I'm now also remembering that I got a Pignose G40V back in '98, and IMO that thing was built like garbage (at least the preamp PCB), but at least it didn't have the tube sockets on the PCB. I sold it to some guy who used it as harp amp back around maybe '08 or so, but I have no idea what's become of it. Anyway, in the 10 years I had it, it also never failed on me.
Anyway, I'm of the opinion that PCB tube amps (specifically) that tend to have failures are due to either design flaws, or assembly errors. As long as they are both designed and assembled correctly, it's not like they tend to have random malfunctions.
Also, it's not just the cheap PCB tube stuff that can be designed or built poorly. IIRC, Marshall (as just one company) has had failures with some of their more expensive/premium amps. I seem to remember there being issues with either the DSL or TSL stuff.
-and if you did did you like it?
Thanks!
I feel like an old fart '60's/ '70's rocker that loves small amps ( me!) really should own one
