Free dual trace oscilloscope

Hello David,

That would be sad. If no takers here, can't you give it to a school? Such a scope should be perfectly fine for simple electronic experiments. Plus the chances that it 'grows legs and disappears' are pretty slim so they'd have to worry less about that.

Heck, I still use my first scope, a 30 year old Hameg 8MHz single trace. No trigger, just sync, but it's fine for most quick checks.

Regards, Joerg

I'd love it, but I'm in Malaysia. Apart from the transport problem we use the British standard 240V main. Best to do what Joerg suggested and donate it to a school.

I'm sure even the local vocational high schools are more state of the art than this (I attended one studying electronics when this thing was made, I couldn't afford this unit then, though I would have loved it. I was really into building stuff in those days, both kits & from scratch. One such kit was a Heathkit 2 1/2 digit DVM using nixie tubes! Anyone else here that old?!? Heath actually had STORES then. I can still picture these very 'scopes sitting on the shelf next to the DVM I bought). They're not going to be interested. As to the 240, it's dual voltage. Heathkit from this period was nice equipment. It pains me to toss it, it really does, but I have a 60 mhz B&K, I just can't take both.

Put it out front, overnight, with a forsale sign. $50

It'll be gone by morning.

David.. My first Heathkit was that DVM you have. I still have mine also. Warren

Warren-I don't actually have the meter any longer ;-(

I had a couple of ( not fabulous but vaguely functional ) Tek 545s that had to be junked when my former colleague moved out of his office premises. No room to keep them.

There's probably health and safety regs that stop schools here in the uk for example from accepting such equipment that doesn't have modern safety certification.

The school might have better scopes, but a lot of the students don't own a scope.

You beat me to it. I'm sure the teacher could find a willing taker.

Hello Graham,

Sad. Those were especially good in winter as they heated the room nicely.

I have the impression Europe is beginning to regulate itself into oblivion. WEEE and all that stuff. It'll kill a lot of small biz.

I wonder, has anybody ever been electrocuted by a scope? I mean not by hooking up something wrong but by the scope itself.

Regards, Joerg

I was on the advisory board of a local vocational electronics course. The students that wanted to be there were glad to have anything they could get their hands on, and several hung around my shop to get some hands on experience. They were very happy to get the older equipment I didn't need, as well as to have access to my library of databooks.

Nearly - when I was a student engineer I tested Thyristor convertors with the earth lead off teh scope. This was 415V 3 phase if I remember right going in. The earth had to be left off to avoid a short and the scope chassis was then live! . First time I left it on and fused all the lights in the building! I have also heard of similar cases where the old scope was on a trolley with castors. The rubber on them was melting!

This doesn't count. It wasn't anything about the scope that electrocuted the idiot, it was the stupid operator and inherently lethal setup.

Thanks, Rich

That reminds me of a story. I onced pushed a button, and a something like a 1000 amp breaker shut down a whole satelite tracking station. I think it was daytime at least. Well the button turned on a big motor which ran the Y axis of a 65 foot dish. The motor had some kind of short, which then shorted out the first breaker box, which then tripped the main breaker a couple miles away.

I'll never forget the feeling!

I shut down a country! I was working for NASA on a 'Cable & Wireless' site in Botswanna installing a shuttle voice link.

Had a motor-generator unit to convert 50Hz to 60Hz for our equipment. Darn thing wouldn't start. I found that one relay in the starter box wasn't pulling in. Got a broomstick and pushed it in.

It only took the Brits 20 minutes to get the station back up. There may have been a trembling upper lip in the vicinity but never a bad word in my hearing. Thanks Chris!

Turned out the entire start-up sequence was important - no skipping a step.

I would love to have it and am not too far away near Pittsburgh. However, I am broke (actually on welfare and foodstamps at the moment) So I can not come get it or even pay for shipping. Sad, I hope it goes to someone.

What would you like to do with it?

It's an old 10Mhz scope and this guy is broke. it's winter and maybe he wants to use it as a heater? I bought 3 scopes last week just for the hell of it. I must post pix when I get around to it. Should give everyone a laugh.

I went to apply for welfare and food stamps once, and it was such an incredible pain in the ass that I just went panhandling. One interesting thing about the welfare office (located just a few miles southeast of downtown LA, I don't remember which principality it was in), was that the only people in the whole joint, out of about 300, that actually looked needy were me and the other white guy.

So, I decided to go into performance art - I'm not really a bum, I just play one on the street. ;P

Cheers! Rich
