BTW, can anybody indentify the equipment in the shop as shown in the last picture of ALF?

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.

a shortwave or c b radio to the right of Alfs head. The signal generator looks like an Eico 324. jr Last edited by jr_tech; 07-14-2017 at 11:15 AM. |

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.

Looks like you're coming along fine.
