    No, fuses are typically ( not always) due to a shorted output. I've not had fuses blown during any matchup. Does one side have the KSC 1845's and the other side not?

    I have had PL14's latch up after installing new caps, that was enough to throw off the power up.

    No it won't make it moot it will only cut out your speakers. If you have excessive DC on the signal outs the DC protect relay unlatches the speakers. It does not cure the excessive DC....

    Yes you can run the amp without fuses, just make sure you pull both rail fuses..dont want to power up with just the positive or negative rail on. No guarantee anything will be hurt, but the possibility is there.

    Yes you can run it without outputs...see in the WOPL archives on the bring up procedure after installing a new control board and backplanes,,,it is applicable for the 14A for what you are doing now. If you can get it unhung by "double clutching" it , sounds like some bad caps or weak...

    Run a pair if 1N4148's back to back , reversed to each other, then solder on the trace side ACCROSS the leads of C6 . Should be 100 uf cap. To get a much better low frequency response, replace that 100 with a 470 if cap..audio cap if possible, because that one does affect ghe signal directly.
