[Central-Electronics] new 20A owner follow-up

[Paul Christensen]

Might there be a published compendium of 20A mods?  I do have the 03/15/1956 CE Change Notice that shows the 20A's evolutionary changes from the factory.

There are a few things regarding the 20A to chew on at the following link. It takes you to two threads.

Thank you, and I'm sure that I will get to the point of asking about SSB tweaking.  I did work through the phasing model some years ago, though I ended up using quartz crystals.  As long as I can stay out of trouble with the 20A by keeping the unwanted sideband acceptably suppressed, I will get back to it.  Thankfully, I also snagged some of the Radio Shack transformers that were mentioned earlier as possible (paired) replacements for the modulation transformers when stores were closing last year.

The way you write about it, sideband on the 20A might well be like going from automatic to manual shift.  Once you go manual, you don't go back.

Again, thank you.
