I`ve tried substituting another EA53 measurement diode in the RF probe, but the zero still drifts quite a bit to my way of thinking - even after a long warmup...
Hi All, I have an HP 5335A with option 010 and an HP 53181A with no oven and plan to move the 10811 frequency standard from the 5335A to the 53181A where it...

The RF probes drift quite a lot. That is why they are the only thing that has a zero adjustment knob on the front panel. They replaced the optical chopper...
I think I may have a few of these in cerdips. I'll look, but it might bea wek or so before I can dig for them. I don't believe it's really a FF, I think it's...
I was there in March while OEM Parts were moving. It didn't look like much of the stock they were retaining was as new as 20 years old. Prices looked to be in...
Greetings, A couple of days ago I posted a short message indicating I have some excess equipment for sale. I did not include my list in the message trying to...
Ken The rules do not specifically preclude listing things for sale. I for one would much rather see a few for-sale emails than the endless discussions slamming...
Ken, I've got a broadband connection so a for sale list is always of interest to me, even pretty long lists. I DO like to know the general location of the...
Ken, you asked and I'm giving an opinion based on what I've seen in the group(s,) not what I've seen you do. My expressions of pet peeves aren't aimed at you. ...
Thanks for offer of MC12040 Oz. I bought a plastic version from ACP. Not quite as good as the ceramic, maybe I'll glue a fin on top to aid cooling, ha. I used...

It might be possible to cheap & nastily fit a TL071 - bypassing the photochopper and amp. This would confirm that the zero drift is in the photochopper amp, or...
Someplace around here I have a couple of 2 meter AMECO preamps with Nuvistors. I received my BSEE in 1968 and we certainly spent some time on vacuum tube...
To be fair, transistors were really not much good until the mid to late 60s, especially for low input currents and RF. Silicon parts were very expensive also. ...
Ken, I agree with the folks (like John) who say post basic information, including asking price. Even a list of 20 items would be fine. Consider this: how many...
