I just picked up a pair of Heathkit as-101 for an obscenely good deal. The cabs need a little refurb but the moulding is intact. Someone took out the original Heathkit crossovers and substituted Altec n501-8a's. Should I leave them in or refurbish the Heathkit crossovers? I notice one of the horn drivers sound a little more saturated than the other with treble( slightly more "sizzly"). Could this be due to having the wrong crossovers?
