Icom IC-751

Hi,

I had a IC-751 once which was a kind of problem child. I had to open it up a couple of times and most of the time it were dried out electrolytic capacitors. Below you will find a couple of pdfs with some more info about just this transceiver. I have been writing about these common problems before but the original file is lost. The pdf as described below was a great help finding problems.
