Happy Birthday!

For many device series types, the N and P are not going to match well. If you can get more devices at a reasonable price, that is always best. Where are you purchasing these devices from? A known supplier? I guess my point is, are they genuine devices? A lot of fakes out there (ebay, aliexpress, dalbani, etc.)

Damn. Bad news Al. RIP Steve!

As I recall, the one built by paradoxper that I fixed for tkam had a bit of difference in volume (not measured) between ZF and SS modes. Close, but not exact. It was close enough that it wouldn't have bothered me. I'll order B on-semi sand.

Kevin, A couple of questions. I have a pair of thru-hole boards which I am planning on building. The BC546/556: Is the C variant still preferred, or is B acceptable? Should any resistor value, etc. changes present on the new PZTA board be used in place of what is shown on the thru-hole boards? Also, I'm noting a bunch of new vendors in the TO92 space since on-semi and I presume nxp are discontinuing much of this. Taiwan Semiconductor, Central Semi, Diotec, Micro Comm. Components (MCC), etc. Are these all equivalent, or would one prefer to use on-semi if available?

Happy Birthday Todd!

One other quick question: the datasheet shows panel depth of 1-10mm. Have you used this on a 10mm panel, and did it fit OK? I'm rethinking doing the cavity inset, but might put a 2mm cavity or so on the back side. Otherwise, just have the hole drilled and use in 10mm panel.

One more stupid question regarding vandal switches. The eSwitch ones I am looking at have 3V LEDs. None of the PSUs in the equipment have anything near this (+/-30V in one, +45V in the other). Do you just use a series dropping resistor, voltage divider, or what to accommodate these? I'm guessing trying to change out the LED(s) in one of these switches would probably be a good time if you fried it

Thanks Nate, but I already have an order in with Modushop and will just need to wing it. I'll probably go a little big on diameter (25.2 for a 25mm switch). I don't have the switches yet. That panel will be re-anodized after machining, so should look fine.

Thanks Beefy. I'll go with 0.1 mm over on diameter, and do the recess at 0.5mm.

For these, if machining a front panel with a 1-1.5mm recess for the outer bezel, would you have the cavity cut at the datasheet size (22 or 25 mm), or would you add a bit to this dimension? The eSwitch datasheets show a tolerance for the overall body, but not for the bezel.

Watching Yellowjackets (Showtime). Kind of a cross between Lost and Lord of the Flies. I kind of like it. Girls HS soccer team supposed to go to nationals in 1996. Private plane they are on crashes. Most survive, and aren't found for nearly 2 years. 20 years later catching up with those who made it out. Something bad happened out there... but no one is talking.

Happy Birthday Bryan!

Missed this one from earlier in the year - Tim Bogert, bass player for Vanilla Fudge/Cactus. https://www.rollingstone.com/music/music-news/vanilla-fudge-bassist-tim-bogert-dead-obit-1114424/ #FuckCancer

Happy belated Birthday!

Happy Birthday JP!

I always preferred oval pads on TO-92s to the standard miniature round pads that most board layout software seems to use, including what Kevin uses. Define your own footprint in KiCad? EDIT: and I'll need to preface this with the fact that I've never listened to a real Krell KSA-5 before, but I don't seem to understand the attraction to this amp versus Kevin's designs, particularly the CFP2/3, but even the SS Dynalo or Dynahi?

I'm sorry for your loss Steve.

Happy Birthday!

I've been doing some reading, and the Systemdek IIX seems kinda interesting, if I could find one with a better arm than the stock ones. I bought (traded for) a Project RPM5-1, and I don't know if it is the cartridge (Ortofon 2M Bronze) or what, but it seems a bit bright and lightweight in sound. Otherwise, I was thinking about something like a VPI Classic? I need to get my Thorens TD-320 out of storage, and see what that is like these days with the Salas phono stage I built. It has a newish AT 440ml(a?) on it, but I've never heard it with a decent phono stage. I also had bought a Grace F9e which I had wanted to try out on it.

Happy Birthday Chris!

Happy Birthday!

Happy Birthday Mikey!

I thought my then-girlfriend (now wife) was going to rip my bicep out when we saw the Exorcist. She won't watch scary movies anymore...

Were the toasted ones drawing the same current? If they are SumR, I'd send them back, with these pics and a good label shot of the 13 yr old one that works. I would think Richard would stand behind his work.
