You could try a FM MPX chip, such as the TDA7040T, a SMT 8 pin device with only about 10 external components, no coils or oddball parts necessary. Powers up with a 3V supply, and output impedance is pretty low, about 5K ohms. The whole adapter could be put in a matchbox.
in on pin 8, out on 5/6, pilot (stereo lamp signal) on pin 7, oscillator and low pass filter (both RC networks) on pins 2/3, and power/ground on pins 4 and 1.

That would probably be more along the lines of what I'm looking for, but it would of been nice to of found an original Magnavox Multiplex Adaptor for this radio but like I said not many of them come up on ebay anymore and when they do come up they ususally want close $100 for them (the cheapest one I saw on there was about $39.95 plus $20 for shipping which brought the price up to roughly $60 which is way out of my price range).
