Thanks to all for the refresher on the 5500 repair. I replaced the 17806P (which I think has a 6v output) with a 7805. This fixed the problem. I had to recalibrate as my max readings in the SatPC32 rotor calibration routine dropped because of the assumed lower output voltage of the 7805 regulator. I could only get a max azimuth reading of 206, somewhat less than the 255 needed, but this seems to work ok.
Does anyone know a source for a replacement bulb in the display? Both my bulbs are burned out and I would like to replace them with something I can obtain locally. Thanks again for all the help...
