Looking good!
I had a quick skim over the new PDF and spotted a few things. I've not compared against the original but here's a list and an image below showing some of the things I spotted.

C7 looks to be missing its ground.

There is a 'C31' and a 'C31?'
I think 'C31?' is C51.

Cap ref des and value missing on pin 14 of the uPD2819. Is this C29 ?

Transformer T01 looks to have gone slightly out of alignment with the net wiring.

C92 C97 text 0.001 needs a slight nudge to prevent a slight foul. This is by the PA driver transistor.

C55 has no value. It seems to be the same on the original so I guess the value is unknown.

Some of the electrolytic caps have a + and some don't.

PL01 logo missing from the bulb.

S01 logo missing from switch near the micro.

F.B. logo missing from Q2022 base.

BATT logo missing from reg unit battery.

LO2 logo missing on tele antenna toroid.

Is it possible to have a text search function? eg to search for C31 for example? I'd only add this feature if it was easy to do though.

It looks like a huge improvement and best realised when trying to go back to the old scanned originals. They look really fuzzy in comparison.
