Right John, the 1st IF has pin 7 and 5 tied together like the schematic. I saw it on the print but it never registered... But this set had been messed with by someone at some point in its life.
Here’s what bothers me about saying a radio works. What I would like is a benchmark. A spec. that says for instance, you put 10 microvolts on the antenna input at 1000 Khz and you should measure 5 watts out across the speaker. Nevermind I don’t have a way to generate 10 microvolts. I just need some reliable benchmark to say I’ve done all I can do to make it work as well as it did originally.
I live 60 miles from the metro area (yeah I'm retired and I love it) and out here we have 3 or 4 local stations running between 1000 and 5000 watts (daytime) – maybe 10 to 20 miles away. Even they don’t seem to come in well.
I have an old TV aerial on top of the barn that I use to connect to the radios. But that is cheating. Does anyone have a way they benchmark their sets???
