Haha... Who was I kidding? I’m a stubborn lunatic. I checked and reflowed all the input and output connections. The culprit was the D+ and D- connection at the OPS. I think the wires got too hot and were twisted too close together so that the melted insulation led to a short. hifiZen wins 1000 Internets for the correct suggestion! Nailed it!
I fixed it!
Now I can permanently attach the front plate as the bottom is off.
Take two for planting it in the main rig...
Happy Days!
It looks like we are estimating an inductance of 120 nH to get a resonant frequency of 55 kHz with the 70 uF cap. So a series resistor of 0.22 Ohms will give a zeta of 2.7, and changing the resistance to 0.10 Ohms gives a zeta of 1.2.
Incredible
Congratulations!I use some similar wire but hey are little thicker AWG20 and insulation don't melt
the reference is SYT(number of pairs) for example SYT2 or SYT5
SYT 1 20 G1 | ET16820539 | CAE Groupe | CAE Groupe 100m Telephone Cable, Aluminium/PET Tape, 20 Grey Sheath 300 V | Enrgtech
If you can find some then give a try
Thanks!
Like xrk said in this or the other vfet thread, I really like the multi-strand tin plated copper silicone wire from Amazon. It’s worry free for my oafish soldering. And a comparative joy to terminate.
Long overdue listening session underway...

And the ranks of FAB increase by one.

Yes, the small solid core twisted pair got a little too hot as I soldered them. My iron may be set on caliente...

I just did the very same thing myself last night. I soldered the wires to the board, then noticed that something looked a little funny when I was done. Pulled the wires back out of the board and saw that I melted the insulation and the input wires were shorted. I was trying to make sure I avoided a cold solder joint on the large ground trace on the PCB.
Like everything in life, there is a sweet spot somewhere in the middle between "not enough" and "too much"
.Have folks who didn't get screws initially received them yet? If so, did you get notice that they had been shipped before they actually arrived? I've gotten a response from the help desk, but no screws, and now (after some work over the weekend) I'm getting anxious to get this thing up and running.
It does look great partially assembled and sitting on my dining room table.

If you have a FedEx account tied to the address they’re shipping to, you can check on FedEx. I believe that’s how I discovered a second package was on its way
Only took 2 business days to get mine.Notified the desk on Friday and got them Tuesday.One the other hand, Canada Post got my wiring pkg. last Monday and still no sight of it.Have folks who didn't get screws initially received them yet?

I had not received a tracking number and emailed the help desk -- about an hour later, the screws were on my front porch...Coincidence or outstanding customer service at DIY -- I'd go with the outstanding customer service...!!
Now I just have to break down and start my build.....

My initial shipment was missing the packet of screws as well. I received a shipping notice from FedEx that the second shipment was on its way and it arrived a few days later. Hats off to everyone at diyAudio and Modushop for this massive coordinated effort.
I feel bad that this happened, it had to have increased shipping costs by quite a bit to get another package out.
