Hello friends of science.
The MANUALS file had to be removed because it grew too large for my free Web Index provider.
All the manuals, mostly related to radio-electronics, tubes, antennas, electromagnetic radiation, nuclear radiation and its detection, etc. are still available and of course always free. If you have a title you need or a subject you want to study, I can still help.
Email your needs to Geo at
Or if that someday fails, wherever I wind up using the internet will always be reachable through my eMail forwarding address:
(Note 0= number Zero not the letter O)
Have fun

P.S, We’re still accepting new manuals, schematics and instructional materials! - PDF form preferred.
