c. somebody drew in another part of the bias circuit in the margin on the same page
d. somebody drew something else in the margin on another page, which looks like a voltage dropping adapter
I'm trying to figure out:
1. who drew the schematic in "a"
2. who crossed off something on the schematic as "b" and what did they scratch out
3. who drew that "c" stuff in the margin
4. who drew that "d" stuff on the last page. it looks like "d" is a kludge to fix an out of spec transformer.
It looks like there are at least 3 different revisions of the circuit all on one piece of paper. It's a mess to try to make sense of it. Can you help me out?
Bob here's the deal. There were several changes made by Bob while we were in the middle of building the amps. Though it looks confusing...it was, 'specially for us noobs. Ask Alex Sauter to get you the link to his beautiful cad drawings. IIRC, they are the last word on the amplifiers' construction. There were some real pros helping us novices out during the build. Roy, Mike, Tom, Mark and I'm certain I missed someone, Bob sat at his desk scoping each one making sure it was operating up to snuff. Bob was a trooper. He kept some long hours.
I have 2 killer amps that I'm proud to let anyone give a listen.
Its going to be used equipment when I sell it, so it may as well be used equipment when I buy it.
