cspirou: I would add an input resistor to ground as well. You can match Q1 to Q3 and Q5 to Q7, but I don’t think matching is all that useful here. If you want to try another small SMD buffer, let me know. I have just ordered some boards now that I have verified their performance versus sims. I can include matched Toshiba JFETs and the other dual package BJTs are available at Mouser.

My Intel NUC also has USB-C video output, so all would be good if someone made a switcher

Recently bought an LG Ultrafine 4K Monitor which uses USB-C (one input and three output). I am curious if anyone makes a KVM with -C output (can’t find any) or what the options are to do input switching on this monitor?

So, what do you guys think of my front panel layout? I would like to loose the indicator mark on the knob, but it functions in four positions alternating between the four options on/off for gain (high and low (MC/MM) and rumble filter (on/off). The LEDs are bi color green/red, green is on/MC and red is off/MM. The power LED is always green. Just using the same value resistor for both colors, they seem to be matched somewhat. The LEDs are from Bivar and the circuit uses one common-anode and one common-cathode. Just for Nate, I avoided blue

I can’t unlock my phone without my prescription glasses. Not the answer you are looking for, but I would assume if you train two faces, with and without, it will work just fine.

Happened to me as well. Took a week longer than the original delivery date but it arrived.

Man I hate casework. I cut this one just a little two close.

Listening is over rated. You need more test gear!!

HC Approved cables FTW!

It’s a good thing Al. Case in point: Old Cohiba band sans holograms - old and antiquated.

No issues with iPhone 6 and current software. I am planning on upgrading, but not because of the software.

Sadly, Alexa only locks things for you. She refuses to unlock

Or just put a zip tie under and solder the top side of the board.

Has anyone analyzed how much capacitance after the GRLV is too much? I would be a bit wary of putting it in a separate enclosure away from its load...

Generally, is there enough “drive” in these “scientific” oscillators to input directly into consumer-grade HiFi? I also would need 10MHz for my Esoteric and would love to try one of these out, maybe you have an extra?

One just doesn’t “ignore” Team 5-pin.

A another question. Does anyone know of an easy way to bend thin gauge mu-metal? To be effective, does it need to continuously surround, be grounded or any other special layout? I am looking to fashion a case divider to separate the PSU from input section of a phono preamp.

Yeah, same rails for both. I am definitely willing to push it harder than 16v - com’on this is HC!

The bits to run the switch are much more low power than the original design. If we can find a small transformer and suitable relay, the rest is easy. Check out Pulse for some options as well as Zettler (which would probably be sold via Allied). Myrra and Block are two other vendors off the top of my head.

I think it’s just a matter of what format would be useful for people. I could see having a small standby transformer board and a separate driver switch / relay combination board. We could also do it all in one. If we can decide on what the physical dimensions would be and a few people are interested, I will draw up the boards.
