I am looking for up to 3 dual banana plug BALANCED - SHIELDED test cables - these cables would have two banana plugs cast in plastic on each end and a third connection (shield) on one end.? I would

Thanks. Reasonable, but I can get decent amphenol connectors for similar / less (when counting shipping), will probably pass. I am familiar with Canare, I like their L-4E6S for audio stuff, used to be

The later HP designed rectifier board for the 8640, complete with burnt diodes. David

Ah! Outstanding. Thank you for the link - that will definitely change this project away ?from having only marginal chance of success! tony

+250V supply is current limited to 270mA. +15V uses an LM317T without a pass transistor so maxes out around 1.5A -15 uses 79UG1C without pass transistor so maxes out around 1A. +20 uses a 21.5V zener

Ah now I understand. You are in luck! Keysight has the operation and service manual for the 1336S which is the 1336P power supply plus a 1336A display. It has a full parts list, schematics and

..you're most kind. I received a stern lecture a long time ago on the Tek group never to leave a thread hanging without a resolution and, being an obsessive, compulsive [former] software developer, I

Thanks for the detailed report on your fix. ?I know it’s never easy to modify a piece of equipment but your fix looks professional and still uses the original labeling. NICE job. steve

He's talking about a 5385A...not exactly "vintage"; certainly not to the level that you're talking about here. -Dave

Many thanks to those who helped in this thread. The advice and encouragement (and proffered manual) yielded sanitary unit and a workaday solution for those who have smashed their gate pots to

I've done that too. It can be a lot of work and messy but it is nice once it's finished. I didn't opt to do that for my 7603 as I've not had good luck desoldering the cans when they're intact (too

I think thy is the problem - there is a mil spec JAE connector in the back with pins for the various supply rails. No idea is any of them are AC. Bw Tony

Don't know it would work with PCB mount caps, but when I restored a bunch of 1940s-1960s Cossor and Telequipment 'scopes, I found that as modern caps were so much smaller for a given

Look in the files section here under “Gerber files” I uploaded all of my gerbers for our various snap-in to pin adapters. Two of them are measured copies of HP’s adapter plates steve

Those little adapter PCBs are an interesting spin on it. I'll dig further into that when I get back on Sunday - maybe they have some that fit these HP Spragues.

If you're replacing a can cap, the ones in the link below work nicely. I just recapped one of my Tek 7603's rectifier/filter boards with them. For the "square" style, he now has two different

Yeah they're primarily aimed at vintage stuff. -Dave -- Dave McGuire, AK4HZ New Kensington, PA

Interesting - what a peculiar specialty. Looks like they mainly do twist-lock tabs with solder terminals, and a few with pigtails. No PCB pins. Jonathan

Hayseed Hamfest manufactures a wide variety of can caps. They did some direct replacement caps for an HP volt meter I restored.
