I have a MTX 801d, where the power connections go onto the amp is loose and can be moved up and down. I took the amp apart and say the points that go onto the circuit board is loose. My question is do I just need to solder these again to get it stable? I can solder but have never really messed with an amp before so I just wanted to make sure it would be ok. The amp plays fine as long as its making a connection which can be achieved by wiggling the power wires connected to the amp.
