Hmmm, long repair queue. Sounds like the makings of a YouTube electronics channel.
There's nothing wrong with leaving things in your repair queue. I don't even want to think about how long mine is at this point. And due to get longer - for reasons beyond my comprehension, I now have a non working HP 208A test oscillator on order from our favorite cash vampire. To compound the lunacy, a service manual for said non functional piece of gear does not, at least after an admittedly cursory search of the usual suspects (KO4BB, BAMA, Keysight and Artek) does not appear to be readily available for less than I'm willing to spend...
To reiterate a comment I made in an earlier post - yeah, I'm an idiot. Why do you ask?

Sounds like you all need to check if a manual is available before acquiring these items. That way they can sit in that repair queue until you get bored enough to do them, safe in the knowledge that you have a fighting chance of not having wasted your money.
No manual available, no buy is my mantra from now on, I don't have the space to collect dud gear any more.
A funny thought occurred to me, i have four 3.5 digit, three 4.5 digit and two 5.5 digit multimeters.
It seems as if my test equipment is ganging together to tell me i need 6.5 next...
That doesn't work though because every damn vendor has different notches and positioning.
I should just buy HP stuff

You clearly have enough for everyday needs. You should consider short-circuiting the unnecessary intermediate stages, and simply going directly to https://www.ebay.co.uk/itm/Datron-Wavetek-1281-8-5-Digit-Laboratory-Digital-Multimeter/282767784359 or the well-known hp equivalent.
Nice metter, enough digits and LED's to keep everyone happy on that sucker.
I still can't find a reason why anyone would need an 8.5 digit meter. Please enlighten me
Really you can't get affordable parts to build something where it would have a measurable use.
To calibrate the 6.5 digit multimeters.
Shouldn't you use a voltage standard for that?

The 5025 unit is a certified reference unit and would be subjected to the same tests as a reference voltage, or reference resistor etc.
It would indeed but when you cal something you need a precision low noise source anyway. You can’t cal an 6.5 digit meter on lower ranges without one. Average power supply doesn’t make the grade. Consider AC measurements and noise bandwidth as well.

Because your forum credits would suddenly soar in value with one and everyone would like you.
ice but I have to say that they also look ugley with chunky corner buffers on them these days.
Something tells me Siglent felt the Keysight pressure to make the designs less similar. Obviously, the original meter was a rip-off, and as the John Kenny interview indicated, Keysight has wisened up.

True for volt-nuts, the rest will kindly ignore your spleen at best or declare you're insane..
Ordered on Oct. 31st I received a small package from chzech republic finally!
Now I can modify my three HP 3456A by exchanging the 5.85MHz quartz for 60Hz noise rejection with the 4.875MHz one for 50Hz noise rejection.
I'm curious if I'll notice any difference.. even with the 5.85MHz quartz the HP 3456A is more stable/less noisy than my HP3457A
