Hi all, I finally got my old R-390A out of storage and set it up for the first time in several years. However, I connected the balanced antenna connection as I always have and I'm getting no signal. I'm getting noise, but it's as if the antenna line is not getting into the RF section. I did the usual things like check tubes, and continuity of the cables, as well as tested the antenna relay, which are all fine. Everything works normally, but the antenna signal is simply not getting into the RF unit. I haven't tried the unbalanced antenna jack yet. I know my way around R-390a's well, but this one has me miffed. Here's the odd thing. When I tune to a strong local broadcast station frequency (880 in NYC) and place my finger on the antenna trim gear, the station then comes in fine. Could it be one of the bypass caps to ground off the trim circuit maybe (C22 in the RF amp?)? I hate the idea of pulling out the RF unit.
