[Amps] 4cx1000 project feedback and thank you

[R.Measures]

>One of the best built 4CX1000A amps is shown in 16th Edition of The Radio
>Handbook.  Saw this one up close and personal as it was owned at one time by
>W7TDK, now W7GG.  But that was in the 60's.

**  W7GG building an AB1 grid-driven amp instead of a GG amp is something 
I find considerably disconcerting.
