[TenTec] 425 titan

[Bob McGraw - K4TAX]

For RTTY it is rated 1000 watts output for 10 minutes of transmit time with 
a 50% duty cycle.  i.e. 10 minutes transmit, followed by 10 minutes of 
receive.  Follow the TUNE UP procedure in the manual and do not over drive 
the amp.  Pay very close attention to Screen current and grid current.  Be 
sure the load/antenna is near 50 ohms i.e. SWR <1.5:1 before starting to 
tune the amp.  Start with 10 watts of drive from the exciter.

 While it is well protected, overdrive can make for expensive and sudden 
tube replacement needs.

And, if you don't have a manual, order one from Tentec.

Bob, K4TAX
