[Amps] SPE 2K-FA amplifier duty cycle

[Joe Giacobello, K2XX]

Typically, you can only be key down for about 10 seconds at 1.5 KW 
before the amp reverts to 1.0 KW.  However, there is a mod which, IIRC, 
only requires cutting a couple of wires, that extends that time to 
around 15 seconds.  The mod is available from Expert Rome, but I can 
post a copy on the Files section of the reflector if anyone is interested.
