I dont think you will have any problems with repairs, old valve amps are pretty bullet proof and the valves and components are still freely available...Last year I went on a vintage marshall buying spree and ended up with three amps. '72 JMP 50, '76 JMP 50, and an '81 JMP 2203
I didn't pay online prices for them, but not too far off. I'm fortunate to have them, although they aren't all original. Changed caps, one of them has a non original power transformer, another has a tube fx loop installed. Both of the JMP 50's have a master volume, etc.
They sound good, but I just can't shake the feeling that they can break down at any moment. These amps are around 40-50 years old. Anyone know what I mean? And I admit that I'm not looking forward to getting them serviced if the time comes. Actually I haven't haven't had them serviced at all since I bought them. Mostly just plug and play for me.
I keep wondering if I did it over again if it would have been a better idea to go for a new reissue JCM 800, or maybe something like a Metro Plex that can get all eras of Marshall tones. Newer, less prone to breaking.
Although I also wonder being an older design, that these vintage amps are easier to repair vs some of the newer stuff.
Another thought that crossed my mind. At what point to these vintage amps become just another clone when parts are changed due to failure, etc.
Years ago... I bought a Sound City 200 watt head.. it was ridiculous.... I dont know where they were made, somewhere in the North East I think... I ran it through 2 4×12 Cabs and I could not get it to overdrive however much I turned it up. I think I got it up to about 4 and it was blowing the doors of the rehearsal room off and still completely clean.
I believe Page had Marshall make him some 200 Watt amps to use for his backline when Zep did Maddison Square
