[Amps] Relay change in Titan 425 help

[R.Measures]

>I want to change the vacuum relay in my Ten Tec Titan 425. It has a Kilovac 
>K41 in there now and Ten Tec still uses that one when repairing the Titan. 
>I'd like to use a Kilovac HC1 (or Jennings RJ1). Is this preferable?

•  The HC-1 or RJ-1A will switch in under 2mS when used with a speed-up 
circuit. This is fast enough to not hotswitch with even a 5mS  
transceiver.   The K41 series relays are slower. 
-  Note -  the speed-up circuit I use requires 100 - 150 volts DC.  For 
those amplifiers that do not have a built-in 110vdc relay supply, it is a 
simple matter to add a 150vdc supply with one inrush limiter, one diode, 
and one filter-C.  See Figure 7 on my Web site for details.
