If they can be removed why are they in there anyway...

And what does C28 do in the set...

As far as I can see the wires seem to be in suprisingly good condition although it is probably best to change them anyway.
Looks can be deceiving.

C28 is a mains filter cap. It should be replaced with an X2 cap as these are built in such a way as to fail open circuit.

I'm afraid I just cut it out....

C2 is best left where it is as it affects the earthing of the set. If C20 is removed, the set won't accept a pick up. No real problem in removing this.

Firstly I will say thank you very much everyone for all of your help.

Where would be a good place to find these replacment parts, and how simillar will a x2 capacitor be cosmeticaly to the original.
The ones I found seems to be rectangular rather than cone shaped as the original is.

Well the BVWS do some parts, you can get parts at meets, or click here - http://www.vintage-radio.com/contacts/links.html .

I use Past Times Radio, but not related, etc.

Cheers,

As you've noticed, they all seem to be rectangular now, with radial (as opposed to axial) leadouts.

What I tend to do is disconnect both ends of the old component, and either remove it or leave it in place "for originality" if it's held to the chassis with a metal clip as they sometimes are. Then, I simply solder the new component to the switched L and N terminals of the on/off switch.

See here (the filter cap is the blue component): https://www.vintage-radio.net/forum/...7&d=1200063483
