I'll have to get to you later on that one.
Still weighing the relative merits of rhodium plated vs silver attachment fastening hardware.

Not a single drool for Yvonne?
Even her name is gorgeous.

Use the U-shaped jumpers' plated thru holes on the main amp board (yellow), to solder an insulated flexible wire for each of the four daughter card I/O signals (bolts).

On the other end of the wire, solder a ring terminal as illustrated in the attachment.

When mounting the daughter card, slide the four ring terminals over the four bolts. (You can make your own decision whether to slide them before, or after, the PCB. Me? after!). Add whichever combination of star washers, lock washers, bolts, and Loctite adhesive that your theology requires. Done.

Now you've got a second, independent current path to get signals and power supplies solidly connected between mother board and daughter board. No longer are you dependent upon the bolts for connectivity. Feel free to use oxygen free copper wires if that's your thing.

Those jumpers would work very nicely indeed.
Even using oxygen free Cu wire lacks the wow factor of rhodium plated hardware, though.

I was just goofing, but wound up hearing a legit suggestion.
Good deal

USPS Package Tracking says a lot of y'all boahs got ye some Norwoods today. Includin' folks in Bald Knob, Harrison, Piggott, and Carlisle, Arkansas. Check your mailbox!

BTW for those readers intimately familiar with the, uh, delightful idiosyncrasies occasionally found in Arkansas ... my wife and I posed for one of our wedding photos, in front of the Bank Of England (Arkansas). It's a double-wide trailer and it's one of our most cherished memories. That and Toad Suck of course. Ain't nobody more revered in our household, than the Army Corps Of Engineers, Arkansas battalion.

A pair of Norwood's did appear in my mailbox yesterday and they seem none the worse for the trip.

Yeah, Arkansas can be quirky. I consider that to be an endearing quality.
My people are from Tontitown.

Here's a test question from a member of the COE Arkansas Battalion, Jeopardy style.
"They call it the mosquito dose."
Somebody that knows about Toad Suck Ferry just might get that one.

Received my boards last Wednesday. Not only did I loose the race, when I went to finish the main board this weekend I realized I had forgotten to put LM385's in my shopping cart at Mouser Looking forward to hearing the "Norwood" this coming weekend.

No idea. Typed from the La Quinta Inn at I-430 and Wilbur Mills (I-630). Raining here like a cow urinating upon a flat rock.

That cow made her way by here yesterday as well.

From the days before we used pesticides to reduce the numbers of irritating insects.
Answer: The shot of whisky that made you drunk enough to forget the mosquitoes.
AKA the mosquito dose, good for what's bugging you.
