May as well post this here following on from my last.?
The radio is basically working but the IF section is not as expected.
The coils do not have any built in caps that I can see, and the cans will not tune down to 455kHz as it says it should be in the book. There is what appears to be a stiffener in the base of the IF assembly it has a rivet going all the way through, but appears not to have any electrical connection with the coils.? Thinking this is just to guide a trim tool
?
The service manual does not show any external capacitance for the cans so I am assuming that it relies on a bit of self capacitance and that of the valves input/outputs to resonate.? I can get the IF's to peak at 530kHz, but one tuning slug is just on the edge of peaking.

The other option is to add a few external capacitors.

Just wondering on peoples thoughts on what I am finding?
