Just went over my 610. I think I got all the bad caps, diodes and resistors. The 610 seems to operate correctly. I notice I can only focus one end of the horiz line at a time. Rocking the focus control makes one end or the other thinner. Is this normal ? Tnx to all that replied to my inquiry on the 610 receive function. bob...w2ami x wn2ami 1962
