Happy Birthday Grahame! And what Steve said

RIP Pat DiGiacomo (aka Jocko Homo), passed away Nov. 4th. Good guy, knowledgeable engineer, but came off as being a bit cranky https://www.diyaudio.com/forums/in-memoriam/362564-rip-jocko.html

Doing a google search (which I assume you have done ad nauseum), revealed an Audio Karma thread which might be of assistance: https://audiokarma.org/forums/index.php?threads/cd-player-belts.345514/ http://www.kenselectronics.com/lists/belts.htm

Last night:

This project on diyaudio implementing a Muse chip for analog volume control might be of interest to you: https://www.diyaudio.com/forums/swap-meet/322983-muses-volume.html

I've been watching it as well, though I'm not caught up (S1E4 was the last I watched). I'm enjoying it, and would recommend.

You mean the 3 parts (XLRs, RCAs and switch)? It seems to though I haven't measured or done any sort of mock up. I think there will probably be enough slop possible in assembly to get them to match, but I'll play around with it. The switch is an NKK m2042xxxxx, and the Neutriks are NC3FAV2. I tied the two chassis gnd connections from the Neutriks together with a pad in the middle, and did the same with the pin 1s. Then put two pads in connected to the board gnd plane. I'll probably add another pad for chassis ground to give the most flexibility. On my Pass Aleph P, the XLR grounds bo

From Rane 110, it appears that the "right" way to do it is to tie pin 1 to chassis. The two pins in the lower right corners of the XLRs are also supposed to go to chassis, correct? If so, I could wire these together to a pad to wire to chassis ground.

Too bad, though it sounded as if she was in bad shape. A gorgeous woman, even at 65. Too young. It sounds like she was quite kind and well liked as well.

Bought a pair of the Vampire RCAs (ebay) and measured them. I've attached an Eagle library with these in them as well as a board layout using these and Neutrik jacks and NKK switch. I haven't verified any of the board <-> panel spacings yet, but they seem reasonable, with some soldering slop. Change the file extensions from zip to lbr for the library file. con-audio.zip

Those caps should run from V+ or V- to ground. The boards have a ground plane (top side of board). Check for continuity to ground on those; if not, jumper them to ground. Sometimes if you use PCB drills and only enlarge slightly, they will still be good.

Happy Birthday Dan!

1) This isn't a headphone site 2) As an engineer, you should already know that nothing is perfect...
