The radio is working, there are a few things to do yet, the volume control does nothing, it is off or on at full volume. I suspect the track is open at one end, I need to take it out and dismantle to check it. It is odd having the volume control in the aerial circuit, I have seen it in other KB radios.
Although the radio is working, the HT is only 95v so I suspect the rectifier is a bit down, the HT should be 195v. I have to do a load more checks, but I am having a break for the rest of the evening.
The speaker is reassembled and fitted beck in the cabinet.
Here are some photos of the re-working of the last 2 capacitors.
I used a 22uF and a 4.7uF cap together to make about 27uF.
The capacitor case was cut in half by rolling it under a Stanley knife.
A washer was made out of wire and soldered so it stayed flat, it had a long end which threads through a hole I drilled in the aluminium capacitor base to connect to the negative leads.
The case was glued together with superglue and as only one capacitor still had a label that one was fitted in the prominent position.
And here they are fitted back in the radio.
