need amp help

[marrstians]

ok... here's the deal... it's a vox ac30 custom classic amp... it took a bad spill last week and has been acting up since... it first started with a squeal between playing, as well as my tremolo circuit and reverb were not working... my first suspect was tube failure... so i swapped all the tubes out (not including the rectifier tube) and it seemed to be working fine.... powered it down for a little bit, and when i fired it back up, it blew the fuse... so, should i be suspecting that possibly the rectifier is bad too, or does it sound like a more sinister problem??? i didn't notice any loose, broken, burned or other problems with any other parts... but why would changing to good tubes cause the fuse to blow now??? help please...

Well, don't rule out coincidence, try another fuse and see. And don't ignore the potential bad recto tube either.
