Zenith 9S232 sensitivity control
#2

If the RF amp is running in Local, I would expect you might get more volume by connecting the antenna to the 6L7 cap. Most likely you might have a open coil in the RF section. A simple ohm meter check is warranted. In my 12S model, coil 1 had an open primary. This caused exactly what you are experiencing. A lightning strike or corrosion are likely causes of this coil to be open. This radio has excellent sensitivity when working right.

If you can't make the switch work, one thing that you can do is leave the switch in the distant position, or I should say wire it so that it is in Distance mode. I believe it is in the open position. You can temporarily use a gator wire between the two points for verification and to test Local/Distance mode so you are sure the RF Amp is working. Most cases It's fine in distance mode unless you are next door to a 50KW station.

Keep us posted.
