Marshall Valvestate AVT150 problem

[beat_major]

Hey guys!
My friend messed up my amp(Marshall Valvestate AVT150) and i was wondering if anyone could help. The input jack socket has been forced into the body of the amp which means you can't connect a lead into the input. I was wondering what i have to do to get inside the amp and fix this and whether there are some things i definately shouldn't do. i hope i've explained this right. Any advice is greatly appreciated, thanks!

Gotta pull the chassis out and replace the broken jack.

COnsidering that the input jack is on its own little board, I think, it might be nothing more than the nut came off and the jack fell inside the amp. Stick it back in the hole and replace the nut, and rock on.

Of course you still have to remove the chassis to do this.

Could be. I was thinking it was sheared off at the barrel like when amps are either knocked over or something's bashed into them...

Oh certainly that is one of the most common things. Just thinking about how that amp was put together. Stepping on the cord breaks a lot of jacks. Then they want a metal jack intalled so next time they step on their cord, it bends up their panel instead of just breaking the jack.

You know after doing this alot to my own amps, I think they designed these jacks/nuts like this!
Step on the cord, the nut pops off, no damage done, just screw the nut back on and it's fixed!

Not if the pcb cracks in the process.....

There hasn't been a day without seeing an amp come in missing one. General rule is if the amp has all the plastic nuts in front, it's probably missing one in the back .

Marshall isolates some of their circuits from the chassis, thus their insistence plastic jack plague(?).

Not if the pcb cracks in the process.....

I've seen the jack solder connections loose, but not a cracked pc board from strain on the jack.
Not that it couldn't happen.

[Gtr_tech]

I've seen it many times where the board is one pc. Jack nut is either missing or gets displaced in a fall, cable plug pushes on the jack so hard it cracks the pcb. It happens....

Cracked boards happen all the time.
