Hello All,

It appears that the 7806 voltage regulator in my Yaesu G-5500 control box has gone bad; the output is measuring more like 10.8 Volts (!).   This explains why both position indicators were off by a factor of 2 (e.g., elevation meter showing 90 deg, array pointing 45; azimuth meter showing 180 deg, but array pointing 90 deg., and so on).

Question---has anybody used a 7805 to replace the 7806 regulator in this control box?

I don't have a 7806....so this brings the next question--anybody have a 7806 (or 2) that they want to sell?)
