Just an FYI, it isn't necessary to open two threads to address questions on one radio.
Perhaps a moderator can merge these together.
Don't know how much electronic experience you have, but that schematic is available
in Sam's AR (Auto Radio) series, numbers AR-54 and AR-56. See here:

Perhaps a member here has a copy they could scan for you.
