HP Oldies.
I am looking for a couple of HP oldies. The 260A Q meter and the 250A RX meter. I can't find any on eBay. These two instruments were carried over from Boonton when HP bought them

Re: 3456A Voltmeter
The low ohms 4-wire for the HP3456A is excellent. I've 2 of the HP3456a, one in cal from a medical company in Minnesota cost me $200, another from an auto-electronics firm in michigan was only $50.

Re: HP-608A Repair
Max, I too had the sticking meter syndrome. It's easy to repair. You remove the meter (two panel screws and two connection nuts) and then take the front bezel off. There is a tiny screw adjustment

Re: HP-608A Repair
What a remarkable coincidence. I have just come back on the list after being on no mail for some time. Most of you are working on somewhat newer things than I am. I just finished putting a 606B and

Re: HP-608A Repair
I am having attenuator problems also, with a Marconi TF1066/4. The attenuator rack, made of plastic, had broken because the generator had been removed from the case carelessly. I repaired it with

Re: HP-608A Repair
Doug, IIRC the 608's had a resistor in the end of the attenuator probe. The resistors would fry if someone testing a transceiver inadvertently transmitted into the output of the

Re: HP-608A Repair
In regard to the question about someone who could repair an HP-608, as I recall Ashley Hall used to work on these units. I believe she is a member of this group, and I note that she is currently

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
