these were allover the Philly scene 10 or 20 years ago, the showmans and twins, every stoner doom band had one for some reason... cleans are inferior to blackface, but not bad, preferrable to say an ultralinear silverface twin (unless you play ska, then the silverface, its THAT sound)... think mesa mk3 or later, or a lonestar maybe. The loud lonestar, not the special. 250GBP is like 400USDish? Its a little high unless its been recapped, its an expensive recap job and it WILL need fitler caps soon. Its a 30-35 year old amp. Retubing isn't expensive really. Maybe $200 US if you're picky about preamps. I would just get a JJ or TAD retube kit for a twin and if it needs an extra preamp for the extra distortion or whatever then buy one tube, maybe a tested new sensor Tung Sol reissue for big, round grunt.
If your VC30 died its similar construction to a bassbreaker or a blackstar and that'll eventually die under whatever stress you're putting it under.... it culd be a PCB thing (probably) or underspec transformers, a lot of new prosumer grade tube amps suffer from both these problems and need to be babied! assuming there was no user error like running without a speaker load, the red knob series should provide better life, it was the last fender series to keep tube sockets off-board as I recall, so tube heat and any tube malfunctions won't take out a PCB. They're msotly still running, right? Its still a mediocre spec PCB though and is susceptible to warping, trace lifting and cracking due to extreme temperature swings. You shouldn't bring it in from the cold for instance and immediately fire it up. It has to warm up slowly. This is good for your tubes and for the PCB. Load in well prior to sound check in the winter. Pretty much only high end marshalls of yesteryear like the JMPs, 800 and 900 series hold up well. They all have off board tubes and also very high grade double sided mil spec PCBs. Fender always cut corners when they went PCB. These days mainly boutique amps like tone king and soldano feature that kinda PCB construction. This is the handwired mojo.... construction stability! Its less consistent amp to amp, but any handwired circuit will be more road worthy and easier to repair on the off occasion something does go wrong. Now the thing the red knob twin ahs is excellent schumacher transformers, same model and spec as the 60s and 70s twins as far as I could tell last time I was in one. This changed in the evil twin. I don't know if schumacher still makes them the same or at all. The only better twin transformer is the triad from the blondes/tweeds and the early dual showmans.
the amp I'm thinking of is the fender super 60.... had to google it. Best red knob amp hands down. Better cleans for some reason, able to get some reasonable power tube dirt in clean, and superior gain circuitry. Spiffy 1980s rack case.
