What is your suggestion to match the specs of the HP3400A AC millivoltmeter’s rms converter with analog parts available today? I’m drawing a line to exclude AD conversion and digital rms calculation. So it stays analog.

totally agree this time
michaelkellett Ebay crap has getting high!! Kynix has it for 24 bucks.
But the shipping is whopping $40. And I’m sure I’ll burn down the first one….
But 0 stock

that model photo pushes "exploded view" to new heights.
I'm used to this:
ggabe So get 4 of them I personally hate sites that tend to screw up with shipping charges! ( but they are the only game in town )
Personally, I do not trust Kynix with a $100 order. They are an open marketplace, and I do not see any reassurance I’m not getting a fake. Same applies to EBay.
Thanks for keeping the convo going. The strange layout led me to look around on ADI's, and now I have a new favorite: ADL5511 for the rebuild. https://www.analog.com/media/en/technical-documentation/data-sheets/ADL5511.pdf
Looks like they gave higher priority to getting that bottom pad connected. DC-wise, what they did is valid. Maybe at 10 MHz, it's still ok to not have that balanced layout...
You get excellent results considering the markings are not right for a genuine part.

Q1 is per AD specs. What's off with that package?
