Got the toroidal on the work bench for measurements. It comes with a powder-coated steel top-plate and a steel thru bolt. I will have to machine a custom alloy centering spud to mount it. There will be no ferrous metals in this case. Good news I'll only have to machine out it's billet housing by @ 0.100 to clear the factory out-of-round windings, but mainly the output wires do make it's major OD 6.7" at that location....

    I would give at least a half-inch all the way around for wire clearance. The sharp bend angle would give me some concerns.

    The wires exit the toroid upwards.Taking off too much wall may ruin one of the design goals for the case to be RFI proof.

    Settled on my final design. Will have zero exposed fasteners and use only one bolt and tensioning nut. B)

    A little more ID than I had planned to remove. Walls should still be 0.350 thick when done...

    The top plate surely won't let any RFI penetrate lol....

    Well luckily I have a spare 3/4" plate from the XS-amp project :)

    My $23 JB inflationary 316S allen head bolt arrived...and its tech drawing was wrong. Was not a true 5" long flat head but 4.75". Adjusting accordingly.

    Would you be willing to satisfy a curiosity of mine by measuring the DC resistance of the primary and secondary windings of your transformer?

    Sure, Ill be on the project again tomorrow. Which leads do you want tested exactly?

    A flat head bolt will measure from end to end, so the bolt you received is actually 5” their print is wrong.

    That is how you measure say a hex head bolt or button head bolt.

    It's an Ebay re-seller I'm sure. Ace Hardware doesn't even carry these. It's funny because you can't assume anything to ASTM specs any more. I've actually received UNC bolts with 90 deg tapers before.

    Thank you! If you could measure from the blue/violet pair to the grey/brown pair of wires. And then from the black/orange pair to the red/yellow pair of wires.

    So not between individual wires, but between those pairs exactly?

    Just saw your reply.. I'll post results with my Fluke.

    Are you pondering how the amp would see the new impedance of the system with a dreadnaught vs a regular IC cable?

    No, that isn't the reason, but that's an interesting point to consider.

    I'll be experimenting with a nearfield SDA set-up and want to jumper (eliminate) the sub-bass drive inductors. I'll take a DCR reading of that when the time comes and post here.
