Thank you so very much this document, it will be a great help to get it up and running properly!
I might even do a complete circuit diagram now that I know how most parts are hooked up from the article. I'll start by checking all of the electrolytics before I dare to power it up, all of those big black canisters are the electrolytic ones. What I first thought was a crystal in its crystal oven turns out to be the dual zener diodes in the oven. /Martin On Wednesday, 21 April 2021 at 17:57:28 UTC+2 petehand wrote: > I can offer you this, from a 1963 Electronics World magazine.
