Yup, guesses are me. So I did measure each section of the condenser, without the copper adjusters installed, with my somewhat flaky cap meter. That section did track about 25 to 30 pf above the other two, depending upon where I set the rotator section. When I installed the copper adjusters all three sections pretty much tracked the same plus or minus maybe 5 pf.
Also, the adjusting cap for that section is in fact connected to the grid of the 27 and to the top of the osc. coil, just like it shows on my schematic.
Now unfortunately I’ve never acquired an inductance meter, so I cant help there on that osc coil. The coil is original. I did ohm it out a while ago and it is 6.8 ohms total (5.2 ohms and 1.6 ohms where its tapped with a 50K.) So I’m assuming the coil is OK.
I’m basically just getting started on this unit – plan to recap and replace any resisters out of tolerance etc etc
Best,
Vic
