I had a working 422/crt screen filter. I could find no one that wanted it locally, so it ended up in recycling. Shame it had the cover too. I was just in too much of a cleanup hurry last year when I

I have recently acquired a 7934 mainframe that has a 7A27 vertical plugin. The plugin exhibits the following problem. Channel 2 works as expected however channel 1 has the following symptoms. When I

I’ve seen the replies to this thread, and have been thinking about it because it would, in my opinion, solve a problem which becomes more acute with every year that passes. Part of my vision for

Hi Michael, You found all voltages present except 100V. But you didn't tell _where_ you measured those correct voltages. Some power lines are passed by the relays, depending on the mode
