re: RS-M45

there is a mistake in the circuit diagram of rsm-45 cassette deck . the mistake is in the capstan servo board. the capstan servo ic is printed an-6633 , while the original ic part number is an-6630, and both ics are not compatible so be carefull and don't rely on the schematic diagram

re: RS-M45

I presume you have a late manufactured unit.

According to the service supplement the part was changed at some point, with later models having the AN6630, along with a label indicating the need to use this new part number.
