I see an EICO Am signal generator behind Alf's right ear. The scope next is definitely not a common EICO 460, but the knobs look EICO-ish. Good stuff, usually in kit form. I assembled 4-5 of their kits, notably a 950B capacitor bridge checker, in continuous use since 1976.

I'm thinking Eico 465 for the scope, with An Eico signal tracer (147) to its left, and
a shortwave or c b radio to the right of Alfs head. The signal generator looks like an Eico 324.

OK, I've got the IF strip aligned. Now onto the 4.5MC trap adjustment. For this adjustment, they require a test "set up" or test detector. It requires a 4.5MC adjustable trap and some caps, resistor, and diode. Here are the pictures of the procedure and the test detector from Sams. Same thing in Riders.





Anybody have any tips on how to do this without the test detector? I don't have a 4.5MC adjustable coil. Unless I can pull one from a spare chassis?

I found a 4.5MC trap on an old Motorola TS-89 chassis and it worked out well.

Thanks Bill.

I finished with the 4.5MC and audio alignment.
I installed the back and all that's left is to do is refurb the top knobs.
