Re: What type of capacitor for R.F. decoupling ?
 

Older silver-mica capacitors certainly were axial leaded, and I've got a lot of them as NOS. Rather fragile mechanically, and wax-covered. There were also some military types covered with moulded plastic or even ceramic, probably the best style in my opnion.
Later, the standard type was covered in a hard red layer, but typically with the two legs from one side, ie radial, for PCB mounting.
I was wondering whether anybody made axial types with the hard epoxy covering, akin to those linked to above, but with a lead out of each side.

I have vague memories of using hard cased axial SM's, brownish colour.

The most common type of axial SM that I came across were waxed covered, there were some that had no covering except some kind of paint, yellow, orange and sometimes white.

I have also, in the past, used the hard cased brownish SM Caps, and those I still have are that type. Many years ago I used SM caps of that type, in different values, wired to appropriate pins of a B9A valveholde, into which Denco Coils of different ranges could be plugged, automatically connecting to a padder cap. of the correct value when the coil was changed.

I have looked without success recently. I had to replace 3 510pF moulded micas and a 100pF in an audio amp (100pFCAP pic attached). I had a few RadioSpares 500pF red which had the horrible metal tape legs. They had been salvaged from some early digital pcbs and had leads only a couple of mm long. I soldered a couple of BTCu wires and araldited along the bottom. Touched up with some Humbrol enamel. I could have extended the wires round the corner and made them fully axial I suppose.
