I've been having to spend some "quality time" with the mower and string trimmer doing deferred lawn maintenance around the Pink Atomic Ranch. With temps hovering around 100°F in North Texas - which is typical - work gets done from around 8AM-12:30PM. I haven't had much time or energy to sp...

Paul - You need to do a video of the Shaker Desk in action doing a cut. I have this "Wizard of Oz" image in my head of "The Machine" being run. A short clip of that scene would make a good opening for your video.

Nice!
Love seeing lacing cord. Reminds me of my Dad and growing up around airplanes.
Very neat work Paul.

I would focus on the buttons.

The product I use which is TechSpray is OK to use on a live circuit.

Sometimes condensation will form which will affect high impedance circuits and cause short term leakage but usually it will break whatever is intermittent.

You might also try a hair dryer.

I updated the Mouser BOM which had a bunch of now-discontinued tape and reel resistor part numbers.
Replacing the tape and reel PNs with bulk made them available.

I measured the THD of the WE111 transformer. A THD sweep and also 60 Hz at 0 dBu and +10 dBu with 0 series R versus 2k series R Measurements are in the PDFs in here https://crush.digido.com/?u=Mastering_Insert_switcher&p=Kirkwood It's subtle for sure, but maybe not too subtle for me. I'll put i...

Here's a question: SW1 is for the series resistor SW2 is to engage or bypass the transformer I want SW1 to be dependent on SW2. In other words, LED #1 will not light and the "series resistor" will not engage unless the transformer is engaged. So I connect the + side of external switch 1 t...

The ZTX951 PNP is slightly quieter than the ZTX851 NPN.
Both are quieter than the 2SB737.

The ZTX e-Line transistors are CBE so they have the same footprint as a 2N440X.

I would try freeze spray.
