Thinking about doing something possibly daft, and just wanted to float it out there. I am going to build myself a mini, and since I have plenty of MPSW06/56, was thinking about using these instead of the PZTAs for the outputs, mainly to look at the thermal characteristics compared to the hot running PZTAs. I know the pin-out is different, but I did a feasibility check with one with a touch of teflon tubing and found it is quite doable. Pain in the ass, but doable. Head-case? Anti-Head-case? So daft you don't know what to say?

There is one layer labeled Inner 1 in the gerber files. attenuatorsmtv42flipground7 - CADCAM READ-ME.doc

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

I think it is in parallel. IIRC 1.43M was a value that was suggested...

AOT is "Adjust On Test" and is meant to tweak the negative rail output to match the positive.

I think we bought ours from Warehouse Sound or some such place out SanLuis Obispo, CA as well! Never liked the L100s though Sent from my iPhone using Tapatalk

^ Almost bought a pair of those back in the day. Bought the floor standing Infinity Monitors w/ the Walsh tweeter instead Sent from my iPhone using Tapatalk

#3 seed... behind Northerners and the dead

Yes, been using Arrow for quite some time now when they have what I need. A bit maddening to see a somewhat small order split into several shipments, each in considerably oversized packages with too much packing and this even when everything is a “ships tomorrow from the US” item...

Check with this guy. Should be genuine. https://www.diyaudio.com/forums/swap-meet/335828-fs-nos-toshibe-2sk389bl-2sj109-bl.html

Sorry, my apologies. I was trying to figure out how to use spoiler tags in tapatalk. I apologize one again; my bad. Sent from my iPhone using Tapatalk
