[TenTec] Amplifier Question

[Richards]

OK...

1)  How long do I need to wait before my Centurion amp is warmed up and 
ready to transmit?  The manual says nothing, and I am sure one should 
not key the exciter too soon.  But... how soon is too soon?

2)   What METER do you guys watch, and why?

The right hand meter has four display options.  I usually watch the Ig 
(grid current) meter option, as the manual says this is the most 
important parameter to monitor.  It says it should not exceed 260 ma - I 
have never seen mine go above 240 ma at any exciter in level.  Just one 
reason I think this is an easy amp to tune.

Does anyone monitor any of the other three meter settings?  If so, what 
are you looking for and why?

The Plate meter hardly ever moves, and the FWD and REF settings do not 
seem very informative, because the scale markings are designed to convey 
Grid and Plate information, not power information - and the PEAK POWER 
meter on the right side more obviously indicates power out. I cannot 
imagine why one would watch the FWD or REF meter setting - but, know I 
still have a lot to learn...

Any ideas?
