i just purchased a vox vt50 off of ebay and it worked for a night and didnt the next day. when you turn it off it makes a loud pop sound. the headphone jack only works if you fiddle with it and the main guitar jack doesnt seem to work at all. now i have to wait till next week to send it out for repairs but im pretty handy with a set of tools. any ideas of what might be wrong with it or how to fix it?

Maybe the tube is dead? When i turn mine off it makes a pop too, so i guess its normal.
^+1 to a refund....

if you're set on fixing it, take a look and see if the speaker's hooked up properly. my guess at the simplest solution is that the headphone jack is just crappy, and the speaker's disconnected somehow.
