Those who are within range of the Seattle area (Bellevue, to be exact) may want to drop in at Vetco Electronics and take a look in their upstairs surplus room. As of yesterday (27-Mar-19), there was a

To expand on this a bit: It doesn't look like any of the chassis have a computer/controller card in them. I'd wager these were expansion boxes from a larger system. Devin -- I'm not sure what part of

...And I just bought one. Although I already have an 'official' Tek leveling head for mine, I can't rule out the possibility of needing a spare (or, simply, a more accurate version of the official hea

I'm ignorant of any formal arrangement between the two, but I will say this: During the time I was taking my first electronics courses at Merritt College (Oakland, California), in the mid-late 70's, I

Fellow Tekkies, I'm sorry to announce the loss of yet another 'brick-and-mortar' electronics surplus place. Specifically, HSC Electronics in the Silicon Valley (or is it becoming the 'Silly Con Valley

Many early air filters were made from a type of plastic foam which degraded and decomposed over time, essentially turning into (very messy) powder. The 502 is most certainly from that era. The good ne

Mine works exactly the same way, but it doesn't seem overly loud to me. Granted, I never measured it with a sound level meter (as, apparently, you have), but I never felt the need to. You might have i

The ACQ board I posted for availability earlier has been spoken for. My thanks to Jim Finch. Keep the peace(es).

I have a surplus acquisition board, P/N 679-4774-02 (from the label) or G9F-2841-00 (from the top copper layer). It was, as far as I know, working when pulled out of its host TDS520. The 'scope itself

<snippage> I have the Metcal DS1, as well as two sizes of soldering pencil (standard and micro-fine) and the hot tweezers. I use them with the MX5000 power unit. Honestly, I consider it the best solde

(Facedesk!) Right, I forgot. OK -- I've posted the two photos in question to the 'kc7gr' album in the group's photo storage area. Thanks, Dave.

Fellow Tekkies, I picked up a 7L14 from an estate sale this last weekend. One of the things which struck me is the bizarre serial number the thing has -- See the attached photo. My best guess is -- Pr

Case in point: http://www.simmconnlabs.com/1401/2606.html I used one of these kits to bring my TDS784D back to life (dying CRT, what else is new?) The result was nothing short of amazing. Happy tweaki

Not per se... It was just a case of curiosity, wondering if there were some hidden reason. But.. Thanks, Dennis. I figured you'd be the one to make the best sense out of it.

Fellow Tekkies, I've gotten curious about the rhyme or reason to the RAMS store's limited public hours (two Thursdays a month, less than half a day). Thoughts on this? Thanks much.

I just discovered that after I'd posted, Craig, thanks. An appropriate request has been sent. Keep the peace(es).

Fellow Tekkies, I just picked up a Ballantine oscilloscope calibrator, model 6127B. Amazingly enough, the unit came with both output heads (boggle!) Does anyone know of a manual for this unit? The usu

Dennis, keep an eye out for electronic loads from Transistor Devices (their 'DynaLoad' series). I've used several, and they were a favorite at Boeing (I actually found mine at Boeing Surplus, back whe

(speechless, deer-in-headlights look) I've been dreaming about that kind of lab space for the last forty years! Either the guy got truly lucky, when he was house-hunting, or that's a dedicated outbuil

OK, I can work with that. I've never seen the innards of a 7854 before, which is where my confusion was coming from. My plan is to create the board in KiCAD, then post the design info so anyone can cr
