Pat:
Oh, I know they are relatively easy to swap in and out, which is why I say
that once I get the hang of the procedure, I'm sure I'll be fine.
And, I think that would go for most other folks on the list too.
What you say here is important, so others like me are encouraged, and don't
get intimmodated about trying.

Subject: Re: Kevin's amplifier tuning cheat sheet
In the old days!! when we had tubes to change it was never a
problem. Occasionally tubes had to be neutralized - that was
something that as a blind man I couldn't do. It involved watching
grid current and making adjustments to stop that current from
showing. Only a problem with triodes and no longer an applicable concern.
Not to demean anyone's knowledge or abilities but the tubes will only
go in the "right" way and the plate cap just presses on to the top of the
tube.
Hope this helps.
Pat, K9JAu
