Hi, not quite sure where to put this question, so I'll start here.
I recently acquired a Mint, Jerrold tube-type amplifier, with 'F' connectors. It is VERY well made.
It covers TV Channels 2-13 and the FM Radio band. All the tubes are fine and I just fed it a 100 mHz signal and it amplified it quite nicely. I cannot find info on the old girl since it was made back in the late '50s (??). When did 'F' commectors surface?.
It has a couple of small plug-in cans on the front panel and I'm trying to determine just what they are supposed to do.
One socket is marked "PIP" and the plug-in is labled "Jerrold Plug In Pad". Simple...
The other socket is labled "AOC" and the plug-in is stamped "AOC SP"..... HUH???
Any info on this thing would be appreciated!
