Back in the late 70s, I built a lot of VHF Engineering kits. I have recently come across all of the kit manuals; and they're still in fairly good condition. I'm currently in the process of digitizing them and will be putting them in PDF format for easy downloading. I will post a Dropbox link as soon as the job is completed.

Included will be the following:
PS-15C power supply (complete with the pinout for the NE550 chip)
TX-144 & TX-220 transmitter kits
PA-50 Power Amp kit
Modifications to add a GLB frequency synthesizer
GLB frequency synthesizer kit and mods (complete)
RX-144C & RX-220C kits with mods and extra shielding to prevent intermodulation

The radios themselves were stolen from my vehicle when I was visiting New York city in 1985; and were never recovered.  Angry

Tom -

Repeater Builders Technical Information Page (RBTIP) has a category for VHF Engineering.
http://www.repeater-builder.com/vhfe/vhfe-index.html

Your document scans, if higher resolution and from clean paper sources,
could replace existing references or be added to existing repository.

You also might donate copies to http://www.mods.dk/manual.php
Anyway it is a good thing to have those copies available as there is always interest in old schematics and manuals. It seems more and more people are digging out their old stuff and trying to fix it.

I have looked at the websites you guys mentioned; but, I believe that their copies aren't as clear as mine. I've included a link to the VHF Engineering catalog for comparison.
https://www.dropbox.com/s/udyy8aoxltht3sh/VHF%20Engineering%20Catalog.pdf
I know that a couple of pages aren't perfect, as I didn't remove the page staples, and they scanned crooked. I appreciate any criticism, positive or negative.
Thanks,
Tom

I'd say people got to be happy that you did the job. Nothing to criticize.
