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

Thank you all for your inputs.

I'll give that a try. Thanks. Regards. Max. K 4 O DS. Email: max@... Transistor site http://www.funwithtransistors.net Vacuum tube site: http://www.funwithtubes.net Woodworking

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.

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

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

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

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

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

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,

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

...........anyone have one to spare. Cheers

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

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

I just posted the excel list I made some while ago, if this helps. Steve G4KNZ.

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
