Lee, I wish you lived closer. I would love to observe and learn from you. You will figure it out. And I can't even do the basics. I need a mentor, and back during my CB days there was a gentleman who helped me with my Johnson Whiteface, and who could have tought me some basic electronics, but I was just too young and wasn't interested at that time. I was probably 10 or 11 and loved the CB thing..My Dad tried to get me into Ham Radio, but I could never get the Morse code memorized, and was not fast enough at sending or receiveing it to get my license. Wish I could go back in time, and learn one tenth of what he knew about tubes and circuits, etc..I think he was a retired TV repair guy or something..I was more interested in building model cars and sci-fi..
Those are some nice output numbers. I wonder why the variance between amps? Were the transformers all hand wound, or is it in the wiring? They certainly don't look like a mass produced item....you can certainly tell they are point to point wired. The RSD, on the other hand, looks like a mass production item, with most everything on circuit boards...I'd love to know more about the history of RSD and how many of those 800b amps were produced..
