That's just it - the 4400 does not have the two electrolytics across the Stereo Beacon that the 440 has. The only cap I can find in the line going to the MPX board is a 0.22 uF cap in the power supply. Remember, I do not have a service manual or circuit diagram for the 4400 since it is such an oddball. I never did call A.G. Tannenbaum to get the manual from him, I got busy and forgot. I guess I really should get that.
The partial schematic I posted in the 440 thread shows two 100 uF caps, but my 440 actually uses two 200 uF caps. But this is not relevant to the 4400 since I do not see any electrolytics in the equivalent circuit for the 4400.
