Wireless Set No. 52 Canadian - Project

[David Dunlop]

As noted a couple of Posts back, the next Step in the C7D Trimmer Cap replacement is to free up the three individual leads coming out of the mid point in the relevant Coil Assembly, to maximize the movement of the Coil Assembly, once free of the rear chassis plate of the receiver.

In the attached photo, these three leads are:

- The big long one heading up to the Pin on the V1C Holder. Valve V1C is the Mixer and this Pin is either numbered ‘6’ in the Canadian Numbering System, or ‘7” in the British Numbering System.
- The medium length lead running to the bottom terminal of the front capacitor C3T on Tag Board DR, immediately to the left of the Coil Assembly. This capacitor is the A.V.C. Decoupling cap.
- The short lead running to the lower terminal of the Tag Strip 1-Way mounted to the left side of the Coil Assembly.

Interestingly, all three of these soldering points show earlier, rather sloppy, soldering work, probably done at 202 Workshop when the two Coil Assemblies in this receiver were upgraded from the factory originals.

A closer look at all the connections on the Sharp/Flat Switch shows the same work having been done.
