UK availability of RF components
 

Other than importing from RF Parts in the US or Barend in the
Netherlands does anyone happen to know of a UK source for any of the
following parts:

Unelco/sprague type metal clad capacitors

25 ohm semi-rigid coaxial cable

Philips 'Blue Spot' or similar high voltage RF trimming cap's, min 300v
working (65pf).

Thanks.
