Help needed: AR1500A Stereo Receiver

[BobR]

Mike,

If the 40673 is the MOSFET, an NTE222 from Mouser will work.  Have used this
device to replace a 40673 in a TenTec Triton, works fine.

My AR1500A receiver has the same symptom but finally went full belly up,
now both FM and AM.  Will be interested in any helpful suggestions you
get.
