content: just buy the classical 34401a, find one with the recent revision display board ---- the one with red and black probes sockets is sure to have itfor the red only input sockets, you have to check the serial numbers ....If the vfd is dim, it is replaceable with clones on Ebay or Ali ,,, it was originally sold with the front keyboard pcb ... but keysight said: its almost out of stock or no longer availableschematics are available etc ....

content: Keithley 2000 is similar spec and has a few more features than the 34401.But :the buttons aren't as good (wear out more)the display isn't as clear (smaller digits)the cloned displays from china aren't available

content: If you are on a budget (or as a 2nd, 3rd ...6.5 digit meter) a Solartron 7150Plus. They go for as little as £50. User and service manuals and schematics are available. You may want to replace the 4 LEDs for the display backlight if it is too dim and definitely (!) replace the power inlet filter which contain RIFA caps that either have already or will blow up soon. They did in mine 5 mins after power-up and the stink is dreadful . Other than that, the meter works fine and is still in CAL. It can be easily re-calibrated (see manual). It has 4-wire ohms using the sockets on the back. The AC volts frequency range is very impressive up to 200KHz still 0.2% . The fly in the ointment: Its AC current range. There is only one: 2A and that is it.

content: The solartron 7150 is quite a bit lower rated than the Keithley2000 or 34401, more like the bottom end of 6 digits. So the lower price is justified. In the UK the availablity may still be reasonable, while the HP / Keithley meters are easier to find in the US. I personally may prefer the 5.5 digit 3478, but it depend on what performance (e.g. noise, low ranges, ohm, AC) is really wanted.

content: Solarton 7150 or 7151+ are actually 5 1/2 digits multimeters. To get the 6 1/2, they do math and are very slow.Other good options for multimetes at same time than Solartron, with less functions than modern ones, are Datron 1071, 1061 (1000V - pay attenption to options installed); HP 3457A; Keithley 196 (both up to 300V only) - all of these I have already had. All fixable and vast documentation.
