Chuck- Funny thing is, I just came across this same diagram in my RCA Radio and TV course from the 1950's about a day ago! Interesting coincidence Icon_smile Thanks for posting it- I may print this one out for keeping handy at the workshop.

Golly, I had that beat into my head so much at Valpo Tech, I really don't need it. But, thanks for posting it. As a sidebar, several weeks ago I had a great conversation with one of my instructors from VTI--Don Wiggins W9CWG. We shared many memories. It was a great time. Icon_razz

I was just thinking same thing about Valpo Tech, when I read the VERY words that I was thinking! Glad to see there are other Valpo Tech people here. And real glad to hear that D.E. Wiggins is still doing well.
I still remember Dean Patton telling us that Mr Wheaton wouldn't be in today, he fell off a barstool at the Franklin House.....
