[AMPS] Instant ON..

[Jon Ogden]

>My point is that very few actually need instant on, they only think they do.

I have a question about all this instant on stuff:

So your amp is sitting there off with the bandswitch on 20 meters.  Say 
you hear your DX, turn the amp on but what happens then to the tuning?  
You still very likely need to tune your amp to operate properly on your 
desired frequency.  Yes, yes, I agree that there is typically enough 
bandwidth that you can move around the band a bit w/o tuning, but what if 
you have moved far enough to change?  What if the amp was tuned for the 
CW portion of the band and now you are on phone.  What if the amp is 
tuned for 20M and you are now on 40?

I know that those fancy commericial Alpha amps have auto tuning which is 
slick.  I doubt many homebrewers get that complex though.  And even with 
the auto tuning, the Alpha isn't instant on.

So what good does having the tube instantly ready to for you if you still 
need to tune the amp?  Or do you hear the DX and just tune up on 
frequency like a lot of morons do?

73,
