That brings back memories. I'd been fixing radios & tv's for smoke money for about 3 years, but when I got a job at A. A. Schneiderhahn Co. in August 1951 where they had a "state of the art service bench" where I serviced all the Zenith Radio & TV stuff the dealers couldn't fix in the all of Iowa and north half of Missouri. Had a Kay Megasweep for alignment, and a Hickok 505 scope, ac, untriggered, but it was pretty much THE stuff in August 1951. I was 16 at the time. I've pretty much had a scope probe or two at hand ever since. At various times I have used quite a few of the tek scopes over the years, and watched them go to hell after the Tek/GVG merger. Today my personal scopes are a Hitachi v-1065, the std computerized dual trace delayed trigger for channel B, 100 Mhz scope first made in about 1985, and 2 years ago bought a gigahertz dual trace sampler. That Hitachi is, after all these years, still within its original calibration window which is why its still my favorite goto. And its brightness fade only shows up in a loss of writing speeds when looking for transients. That little pocket DS-201 I bought 5 or 7 years ago now? It still works, but the battery has swelled up and pushed the case apart. Its bandwidth turned out to be less than useful around this machinery the instant I bought a Mesa 5i25 & put it in TLM's controller. > And, a GR DigiBridge, very handy piece of gear.

I also bought an HP Vector Voltmeter several years ago with an eye to building it a new probe, but gave up when I found the probe, which was missing from this one, was a separate service manual. At one point in the tail end of the 60's, HP could sell you a new one for around $1600 bucks, but because it was so critical to get the sample timing dead on, they had to have the whole thing. So I've a nice bench box that may someday yield a couple good 6 or 7 inch taut band meter movements. For what I paid for it, about $225 a meter. :( Its been quite a ride since I quit school in 1948. > Jon Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
