i have a late 80's Maganavox stereo model EC9350 that i use as a spare. the unit has worked fine for years, but now i have annoying pops and static coming from the speakers whenever the unit is turned on...even when there is no signal being sent...the static comes from both speakers (i've tried switching l to r outputs but same thing happens)....if the amp is blown is there anyway to fix it?

Yes if it is blown, there is a way to fix it, but it would probably be cost prohibitive.
Chances are good that some connection could be loose either inside or outside of the amp if it is snapping and popping. check your connections on the outside, and poke around the inside with something non-conductive. I have a wooden chopstick I use... or a drumstick.
I would guess it is the device selector button(s). AKA the Radio/Cassette/Auxilary selector knob or push buttons. They usually seem to be the culprits in my experience on old stereos. the other portion that causes popping/crackling in my experience is the volume knob. wiggle any of those to see if it causes the popping.

if you are taking the unit apart, also make sure all the grounds are making good contact. if has a stk, especially look for bad connections, but be careful not to bridge the gaps between the leads with solder.:)

Have you cleaned all the switches?I would do this first.I work on old radios from the 30s and 40 and find that the switches get gunked up.
I use plain old lighter fluid soak the switch with the unit unplugged and work the switch while fluid is cleaning.
