LM399 Voltage Reference, Fluke 289, Gossen 29S, RM303, AN870
Trader:
Just For Fun !!!
Jumps J8 and J10 are a stable 10.004 kOhms resistance.
J7 and J12 can keep a relatively stable capacitance of 156uF.
(other combinations also work with different values) (turn it off first)
J-R:
If you want a budget reference you can rely on I would suggest the excellent VREF-01 from voltagestandard.com for only $31. Calibrations are free for the first 2 years.

I tested this reference over 24h with 34410A and 33401A and so far is very stable.

34401a 9,85787 9,85784
