The good home had the system operational for a few years before it was sent to the bad place... Steve WB0DBS

Dear ?yes please, when you have a 8563e please send me a mail. BR ?diego gustin

Building a 11683A isn’t as simple as using an old 8481A and a few precision resistors. The range switch in the HP 11683A is not your run-of-the-mill SP 10 pos rotary switch. HP used a very low

An 11683A, 432A plus 478A-H75 sensor, a counter and a DMM. 11683A is rare, but you can make one from a dead 8481A (and there are plenty of those around):

Well if it was, I'd sure hate to be in a bad one!

Ugh. That doesn't sound like a "good home" to me. -Dave -- Dave McGuire, AK4HZ New Kensington, PA

Roy... I'll assume your first sentence needed a sarcasm font. ? I don’t recall anyone asserting that they believed that they had a NIST traceable cal setup, but there was an implication, as you

Don't worry, I save way more time with this group that I can ever give back, so it's really my pleasure. I'll upload it an other way (not zipped, so everything can be download once at a time). I'll

I wish I still had it but it went to a good home when money was tight. I’ll check but I’m afraid it was probably crushed for scrap. Steve WB0DBS

Hi James, Have you managed to get hold of a copy of the service manual? So far I have not and my 9673G suffers from low output. Generally 30 dB too low, so I suspect the final amp died. The attanuator

Hi have here an oscillator and need schematic and pinout for test. Does somebody has a datasheet of the YIG? Best regards Armin HB9MFL

Orin, Glad you chimed in! I have couple 436's and when I auto zero they tend to drift a little after short period of time. I thought my sensors were at fault since my room has window AC nearby causing

We would SO give that a home at LSSM, if you still have it, or know where it is. -Dave -- Dave McGuire, AK4HZ New Kensington, PA

Not a Cray but I had an Intel iPSC sitting in my living room for quite a while. Got a lot of attention from Intel and others. Steve WB0DBS

Someone needs to tell FexEx and UPS that, because they still keep trying!

Good heavens. Please don't do this, at least not here. They really are well thought-out designs. Even FedEx and UPS can't kill them! -Dave -- Dave McGuire, AK4HZ New Kensington, PA

short for "your". To stay "on topic", I've collected 4 or 5 of the 435's just to have the cal. source that's inside. I know they are old and the freq. drifts on them but the output level is what I

It was effectively instantaneous, as expected. ("ur"?) -Dave -- Dave McGuire, AK4HZ New Kensington, PA

Interesting thread! Dave, so how long did it take the Cray to balance ur checkbook?
