Nothing wrong with the build quality of the JC-1! It is nothing short of amazing to get the parts quality inside that those bad boys (for the money or any other way you want to express that)exibit. I have seen a lot worse out of some much more expensive products.
I didn't warm up to the amps (but it could have been an issue with breakin, want deny that) but they were a couple of the best built amps I have seen.
