Success...

After replacing the audio coupling capacitors, I tried the unit out on headphones and it sounded fine, so I decided to button it up and go no further with it.
The Stereo Beacon is still the original incandescent bulb. I took some voltage and current readings in order to plan for a future LED Stereo Beacon conversion. The multiplex adapter receives +15 volts from the power supply; this voltage drops to near zero at the multiplex adapter when a stereo signal is tuned in. I measured 28 mA being drawn by the incandescent bulb.
So that is it for this Fisher 200-T. It is good when repairs are this easy.
