One thing to note about the S6 is that it is a feedthrough input.? And, as mentioned, since it has no 50 ohms internal load, it's very susceptible to static damage.? I keep a 50 ohm load on the

Have fun with your new toys! Two things, different from general purpose 'scopes, that you need to be careful with in order to stay happy: The S-6 input is pretty easily damaged. Its characteristic

Are you referring to the 7623 or the 7B70?

Yeah, I figured it was worth buying it. For the little background story. The guy works at “DASSAULT AVIATION”. He told me they have just quite recently changed their machines and they were just

All of the micro switches I have used for microwave door switch repair have been "generic" devices from my junk box. Some were even collected from junked microwave ovens! Ken WA2LBI

Did I? OK. LOL

RIFA cap, in a 7623? I haven’t been inside for a few years, but I don’t recall any… I would power it up without the fan turning…. Or maybe with a Variac and current limiting bulbs…

It does move the trace from left to right, and vis-versa, yes…

Hi Jim, The problem was a broken cylinder inside the cam drum. After I separated the front end cap, everything came out and I was able to glue the broken parts and then glue that back onto the end of

I'd love to see (got photos?) and hear what the problem was and how you fixed it.

That's what's in our microwave oven. Generic switches have always worked for me. Our local appliance service place had several options to choose from.

Some of the newer 2430As used those Dallas type chips. I have one of each. Vince. -- Michigan VHF Corporation -- nobucks dot net K8ZW - http://www.hamradio.fun

Hi Manuel, It's a long time ago, as far as I remember the problems that one had were quite typical for the 246x series. (I know now) A5 capacitor leakage, reference voltages wrong, DA converters in

The micro switches are generic, I used to salvage the good ones out of dead/discarded microwaves. Simple ohms test will show if the contacts are bad...

Leo, What did you ever find out about this? Manuel

He did.

Ali Hajimiri is always doing some interesting research. I used to look up his papers all the time when I was working for a chip company. High-speed optics, microwave chips and antennas, oscillators,

The George Carlin school of indexing. It’s been with me for something like fifty years. DaveD

Hi Roy, I didn't buy it recently. I got two of them back in 2009 or thereabouts, and just recently got around to going through them. I just listed the complete one on eBay if you're interested:
