Re: Mini Dynalo I thought I had posted this here, but apparently I didn't (had some PMs going at the time). When I was getting ready to ship the last mini out that I built, I noticed an odd problem in that occasionally DC offset on the SE would jump to ~500mV at startup. To make a long story short, I determined via scope that the Meanwell bricks don't always start up at the same time. When the + comes up first, the servo opamps freak out briefly, causing the offset. Without the 0R jumpers in you'll never see this. And it only affects SE output; the balanced output offset is always fine. A month or so ago, while perusing diyaudio, I ran across a comparator circuit used for power management in, of all things, the O2 amp. This circuit, placed before or after the regs, with proper parts selection for voltages, would cure this "problem". I realize virtually no one would build one of these for SE output use, but one thing to be aware of. If you are using SE phones with these, wait about 30 secs. before plugging them in. I did PM this info, and this circuit to Kerry, but he has a lot of fires burning and redoing the mini probably isn't even on his radar

RIP Niki. Rush was a hell of a movie!

Garbage - The Riv

Apparently HBO had said they would support more seasons but it was the show runners and writers who wanted it over. It should have been stretched at least another season to give things more breathing room in my opinion. Dany morphing into her brother that fast didn’t seem quite right... Now I’ll have to go back and watch the post credits thing as I didn’t leave it on long enough. I was thinking when Jon and the wildings we’re leaving Castle Black that there’s gonna be a white walker appearance (as in the first episode)... Sent from my iPhone using Tapatalk

Thanks all! Not a bad day at all, though I did work all day downtown. Came home and both sons were there (with the younger son's girlfriend). Had a nice dinner and too many 3 Floyds Space Stations. Overall a good day! I took today off hoping to go for a semi long ride with my younger son, but the weather isn't cooperating. I guess I'll just take it easy!

When I did the adapters (and built my SS Dynalo), I had looked into this and this is what I used: C -> D B -> G E -> S

I would just use some IRC/TT RC55 0.1% resistors such as 756-RC55Y-750RBI (Mouser) and be done with it. The Texas Components resistors will run on the order of $15/ea... Sent from my iPhone using Tapatalk

RIP Doris and Peggy as well. Doris lived a good long life, though it seems like things in her personal life and experience(s) with men weren't so hot. And Mod Squad... hehe, right on that that was the hippest show on TV back then. Solid!

Happy Birthday Ari! Hope you have a great one!

Happy Birthday Shelly!

Any of you ever across this stuff? Discrete opamps and 78xx/79xx Vregs? https://sparkoslabs.com/ Wonder if the regs are any good and how they compare to Amb's o78/o79?

Thanks Purk... I appreciate it! Sent from my iPhone using Tapatalk
