It may have been a weak batter in my MM. I changed them out and my readings are closer now but still a low on Pin 6. Here is what I just measured : PIN 4 was 5.26, PIN 5 was 13.26, PIN 6 was -7.99, PIN 9 was 5.26, PIN 10 was 12.75. These are bench tests on the Sony PSU with no loads...

Lol, never a dull moment learning electronics! My background was software development from mainframes, client/server tech, to C# and .Net. Now retired, I love the challenge of learning what I can from all you marvelous electronic geniuses! I can't get enough of y'alls videos! Greatly...

I went back and cleaned up a few solder areas where I didn't pull away and get the teardrop just right. There may have been a few that maybe hadn't been getting a good connection. I remeasured along with your Sony recap video and now my 5 and 12 volts are normal looking. I copied placing the...

Hi JDW! I enjoy your vids! Yes, I was trying that. PSU on worktable and measuring from there very carefully! I was working with ChatGPT to get ideas, voltage expectations, etc. and seeing where that rabbit hole led! I'm not trusting ChatGPT much. My MAC SE is basic 1MB RAM, 800k Floppy...

Will do. Thanks 😊

No, that's why I thought recap would fix. It hadn't run in a while. I'm going to keep researching. Any ideas?

Good morning all, I recently watched JDW's recap vid and did the same on my MAC SE. In checking voltages, my 12v lines are in spec but my 5v is coming up to 7v. I adjusted the voltage pot to try to reduce it, but of course, the 12v reduces down to 10.45v or thereabouts. Question (since I am a...
