[Amps] Grid Dipping the Pi network in a new amp?

[Tom W8JI]

By the way Chuck, I really don't see anything significant 
wrong with your layout. It looks clean and has reasonable 
lead lengths. Overall it is one of the better homebrew amps 
I have seen, and I've seen hundreds.

I wouldn't change a thing at this point.

The only thing that bothers me is the red on the vacuum 
capacitors bells, where the vacuum caps are grounded and the 
dull or satin look to the aluminum. You know of course 
aluminum oxide or anodized aluminum is a very good 
insulator.

I also hope you are sweeping the tank with the GDO, and not 
just sitting on one frequency hoping things hit.

Did you listen to the GDO on a receiver? Is it calibrated 
and running OK? Does it work well with other resonant 
circuits?
