On some of the capacitors, there are trimmers mounted on the side the varicaps are installed. The trimmers can be a source of drift, so removing them can help stability. Unscrew the screws, lift the copper piece over the soldering tab and bend back and forth to break off. The arrow shows where the pieces are broken off. Remove the mica insulator. The picture shows the sequence of the removal of the trimmers. The one on the left end, which is not on all the caps, is unsoldered. |
Two sections at each end of the main tuning cap are tied together for more capacitance. A jumper wire is used to tie the sections together. They are only tied together on this side. The connections to the stator on the other side of the capacitor are used to connect to the VFO. |
