Re channel imbalance most of the time it's the pots. With age they generally degrade and will drift. You will get channel imbalance over time especially if it's still got them A&B pots, ALPS generally tend to fare better I think.
The A&B pots on mine were totally shagged.
It could also be the resistors around the balance pots. Balance pots are set up as voltage dividers from memory.
Re no output, check the pins on both the mainboard and the summing card.
Are you getting voltage there? Is audio getting there?
