Re: 3456A Voltmeter
The nice big old lab/bench type DMMs will usually be a good deal in terms of performance v. price, since most people are looking for more modern, smaller types. Unless you plan to become a volt-nut,

Re: HP-608A Repair
Steve, Thanks for the comments. I was sure it was not worth a whole lot so I appreciate your perspective. Yes, I do have room for it. And, like you say, if I don't have to pay too much to repair

HP 11660A Shunt for HP 8556A
I may have missed it somewhere but I cannot find any details on how the insides of this shunt is made. I assume it is a pure resistive divider with something like a 550 ohm resistor in series with a

Re: HP-608A Repair
HP 608D's are good units, just big. If you are going to use it and space is not a problem, by all means fix it if you do not have to spend too much. But keep in mind the market for these is very

Re: 3456A Voltmeter
I'll say- I have one of the first HP nixie DC voltmeters (I forget the number); in auto mode it constantly cycles. I only keep it because it works flawlessly and it was the first piece of HP gear

David, You are absolutely right, I should have checked before I posted the link. Apologies to all, I guess that error puts in question all of the rest of the list too! Regards Greg vk5xgh

Re: 3456A Voltmeter
I paid 100$ for mine abour 2 years ago. Love it because of the front-panel math and use it over my Fluke 8085A -- Anders Gustafsson Engineer, CNE6, ASE Pedago, The Aaland Islands (N60

Re: 3456A Voltmeter
I have over 40 multimeters, from a 1948 GR1800A upto some 7.5 digit meters. Also nuldetectors, electrometers, sourcemeters ect. So i do not think you have to many meters. On topic, that is normal

Re: 3456A Voltmeter
Gang... Well for my money, the 3456A is the best DMM HP ever made. While there are ones with more digits, the 3456A has outstanding stablity. Another is the front panel math functions that let you

Re: JFET type? used in 8558B SA
Oddly, that file lists the 1855-0062 as a 2N1595, which is an SCR!

Re: 3456A Voltmeter
Thanks Orin, couple of them on the bay right now with 10k resistors connected up. $275 is what the seller is asking. Seams a bit steep. Granted there is some kind of confidence that they are working

Re: Parts to repair an HP 6434B 40V 25A power supply
Take the bezel apart, and glue it back together. If you are careful, it should even look ok. Bakelite glues ok with cyanoacrylates, and most every other plastic does ok with a thin solvent glue,

Re: 3456A Voltmeter
To be honest I'm not sure if it has the option or not. I do however have 4 good condition sub-c NiCd's standing by just in case. I'm trying to justify the 3456A. While I do some reasonably complex

About $100 if it's working with unknown calibration from looking at recent ebay sales. Goldenrubi on ebay has sold a couple that were working and recently calibrated at $200 obo (he'll take

Re: 3456A Voltmeter
I have too many meters. Well, too many I don't use, like the Ballantine 300, the HP410B, and the Heath AV-3. But I would love a 3456A or similar. Oh and I have a 5-digit job from about 1962,

Re: 3456A Voltmeter
Jeff, Did you get the 8050A with or without Option 01 (internal rechargeable battery pack)? The battery pack is four 1.2 VDC NiCd batteries, two on each side of the back of the PCB, that are tabbed
