I have a Kenwood C2 on its way to me, and I was thinking of a full recap. One can buy a recap kit for this unit online for about $16 (all Nichicon caps). While I'm at it, I was considering replacing the original op-amps (NJM4560). I've read that the power supplied in this unit is greater than the +/-18V of these op amps, so replacing them with something like NE5532s (+/-22V) would be desirable. Does this seem right/advisable, or is there some other consideration I may be missing here?
