I liked the schematic scans that Nick did so well, that I extracted the 6
schematic pages and 4 other extra wide pages and put them in a 10 page
pdf.  The content is as follows: pages 1 to 6 are the complete wide
schematics (in the correct order), 7 and 8 are the filament and heater
wiring and the chassis harness,  and 9 and 10 are the tuning system and
gear train.  I've not seen these pages so clear when you zoom in on them.
Try it on the schematics and the gear train (so easy to see).  You'll love
it.

I corrected the schematic on page 3, the 2nd crystal oscillator.  It was
missing the input to the oscillator grid from the crystal selection switch.

I added about a half  inch of schematic to page 5 on the far right end to
complete the circuitry for the AGC function.  Sorry, it could be aligned a
little better.

I reordered 2 of the pages in the schematic section.  They are now in the
right order.

I don't have a public place to put them at the moment, so if you'd like a
copy, let me know.  It's under 4 MB in size.  It's really nice for viewing
online, and I think for printing but have not tried that yet.

Regards, Larry
