Dymec 2460A/M3 plugin manual?
Any chance someone here has a PDF of the manual for these things? I've found some hard copies on eBay so that might be a last resort, but if I can avoid spending $50AUD just for curiosity that'd be

HP 606B Frequency Dial
Hello Group, I am currently restoring a HP 606B. Unfortunately, the dial markings are badly scratched/worn. Does anyone have, or would care to take, a high-resolution copy of this dial? The dial scale

Re: 8510C - calibration 3.5/sma
Hi Leon, it depends on how accurately you know the properties of your cal elements. Do you still have the kit parameters of the manufacturer? If so, do the standards still obey these parameters, i.e.

8510C - calibration 3.5/sma
Hello group! Is there anyone here using the 8510C with a mechanical 3.5 kit? I have a mechanical 3.5mm 26.5GHz cal kit, but my port cables are 18GHz SMA. What is the proper calibration sequence for

Re: Another draft: 8160A
Unfortunately, the gold plating on the many boards in these makes them a target of the gold scrappers. I am lucky to have one of these generators in excellent condition with the 020 option and use it

Re: HP8560a smoke came out
I think the problem is not really correctable given the circumstances of a system that injects power back into the grid. The problem is that losses are against you. When you draw from the grid, your

Yes, I'm sure solutions do exist.?? I'm more likely to either find higher rated caps or just leave them out. Glenn

Re: HP8560a smoke came out
Someplace, somewhere, you might be able to find a voltage regulator.? I suspect that they can be either the saturable reactor kind, or perhaps an old servo/motor driven autotransformer.? It's

Re: Mounting HP Iron in 19" Racks
All of my 19" racks have mounting holes front and back, as usual, but also have mounting holes on the sides as well. I drill pieces of 1-1/2" aluminum angle to fit the mounting holes on the side when

Re: HP-1421A Q109 Voltages
I got a chance to test the circuit just a bit. I placed a 47k resistor between the base of Q109 and ground. That caused the lamp to illuminate so the transistor is still good. I just need to determine

The cantilever shelves work great. Especially for the smaller stuff, like putting two 1/2 width units together. I have used a lot of Navepoint stuff in the past. This is an option that I like for
