I've received the manual. I am going to go through the counter tests to isolate the fault. I suspected the unobtainable? EECL front end chip. Just in case, does anybody have experience replacing it

I don't think it's the EECL prescaler or any other EECL in the counter assembly, it usually makes the high frequency input dead. However I've succesfully replaced the EECL prescaler with a modern ECL

BTW, there was a discussion going on on the ChromForum that points out that Peak96 obviously needs a special cable to run properly: https://chromforum.org/viewtopic.php?t=16617 pinout Peak 96 Data

...another approach would be to look at the description of the instruments and SW that are supposed to run with the 3396B, for example the 5890 GC documentation. I added a description that details out

You are by far more likley to have a failed counter IC, these are a unobtainable HP version of ECL logic. George G6HIG

Jon, it worked fine until a couple of days ago. No doubler installed.

Hello Martin, maybe the Agilent 3396 Series Integrator BASIC Reference Guide might help here? Please see attached. The Agilent website mentions the 3396-90335 manual as obsolete (which initially was a

Bonjour I dont comprendre if it was OK and now changes or it was always that way. Please clarify, counter indication was first OK and something changes or failed or it was always bad? The behavior of

Yes, it's mechanical; I did mention this a day or two ago, I guess it just went by. Fortunately they're not difficult to remove on those boards.

Not? a problem. How technology has changed, though.? I remember single hole electrolytics that mounted with a single nut.? Inside, I think, may have been a boric acid solution.? Of course, the

All, Disregard previous 70900A power supply capacitor statements I made. A case of head improperly arrange on my anatomy. My apologies. What’s is now realized…duh The blue caps on the PS are NOT

Many of the typical capacitors with metal cans have more than one ground lug, arranged in a circle.? The lugs are, IIRC, only for grounding and mounting stability.? On the capacitors I've seen (not

Thanks Kuba, Yeh coming from the era of tubes I had assumed a dual cap…so much for assuming. Now that’s starting to make sense with the single component designator, but leaves the question which 2

Working on the PS board of the 70900A and bought the CLIP from Artek. Beautifully clear images, excellent for what's there. Unfortunately, the one thing I really needed it for isn't, that being the PS

My assumption would be that the number of legs has not much to do with anything: it’s a single capacitor each with 3 or 4 legs. Very common in that era. I’ e got lots of contemporaneous Tektronix

Thanks Paul, Just got the component location PDF on the site which provides me the PS cap numbers; also ordered the 70900A CLIP. However, looking at them I’m confused further with the 3 leads. Only

Hi Gene sorry made a mistake the 3 legged caps are on the Vishay N -cap ?and can be found on the hp 70000 groups site. Regards Paul
