[Amps] Capacitor

[Karl-Arne Markström]

The description fit in on TCC ceramic high-voltage capacitors of early 50's vintage.
Similar capacitors were used in the Standard Radio CT5 5 kW CW/FSK transmitters (CV445 or 5J/180E forced air cooled pentode PA) that were used in large numbers in Sweden.

Capacitors in these transmitters had a 10 kV peak dielectric rating, and a kVAr rating of 5 - 8.
They were used both as parts of Pi-L networks, and for plate coupling and DC supply decoupling
purposes.

It is likely that the marking "KO.3551/S".  refers to a customer reference code

      Has anybody any information or links on old TCC (Telegraph
Condenser Co.) 
      ceramic high voltage capacitors please? Usually referred to as
"mushroom " 
      style.  Are marked T.C.C. "KO.3551/S". 
      However is marked 1200pf. Grey, tubular, approx 28mm diameter and
100mm long.
Breakdown voltage? Suitable for rf coupling/decoupling?

      Is the KO number a catalogue range or just an MOD supplier/factory
code? 

      Thanks! 

      Andy SP6AEG
