Re: [Amps] Comet vacuum variable capacitor data

[Radio WC6W via Amps <amps@contesting.com>]

Hi Alan,
   The minimum C is 12pf

   30A @ 1MHz & 2000pf

   70A @ 10 MHz at any C

   40A @ 30 MHz at any C

   It is a direct pull (no screw drive) unit requiring 17KG max. pull.

   Incidentally, it is rated 3KV operating / 5 KV test. 
 
73 and very dark by you,

 There is a Comet vac variable on
 fleabay with the part number 
 CV05-2000G/5. I think it's pretty old. OK, so it is 5KV test
 and 2000pF 
 max capacitance. But can anyone identify it further?
 Specifically I need 
 to know the minimum capacitance and the RF current handling
 ability 
 (ideally at both 1.8MHz and 30MHz rather than the short-form
 data at 
 13.6MHz).
