The AS3360 is totally different compared to CEM3382/PA382 (e.g. 14 pin
package instead of 8 pin). I don't think that it will work even if you would
built kind of an adapter board.
I think you will have to look for a CEM3382/PA382 e.g. on Ebay. But before
that I'd check if the quadrature VCO is working (sine/cosine on Y1/Y2). Even
if the VCO is not working it is not 100% sure that replacing the CEM3382
will solve the problem. It could be also another fault, that causes the
malfunction of the VCO. As already mentioned the A-126 is a very complex
circuit and the repair requires a lot of electronic experience and
understanding of the circuit (dome filter, quadrature VCO, ring modulators,
mixer ...).
You may also send in the module for repair. But you have to keep in mind
that we also have to search also for a CEM3382 provided that it is faulty so
that the repair may become a bit expensive.
