I binged watched Stargate SG-1 a few weeks ago, and I did see briefly see which I believe to be a RM503, in the intro for an episode in season 3. Beginning of the episode started in Major Carter's

I can't even remember the model of the scope, but it was one of the old black fluted knob models, from around the time of the 512 or shortly after. It was about 1967 or so and I was repairing test

Oh, yep, there you go. Disregard my last message. That's what I'm talking about. I think this is one of the features of a pre SN B250K. I'm only guessing based on the now two examples. I don't know

Stephen, Compare your scopes TIME/DIV B-sweep knob and HORIZ DISPLAY A button to the picture of my pre SN B250K. There is no "LOCK KNOBS" text on them. I'm presuming this is a pre SN B250K feature. I

Correction: more like 19 V

The motor Siggi mentioned earlier is sold, but the seller has listed another one, that seems to be a 24 V version; in case someone is interested:

I had a very similar experience with a large ceramic capacitor (about the size of a quarter) in the power supply of a 475 or 475A I was working on. I traced the bad supply rail to what appeared to be

On my 1S1’s heater regulator board, the pass transistor was mounted with the emitter pin touching the heat sink, which shorted collector and emitter and ran the tubes hot. Dave Wise

OK, not in a movie or advert, but in a Web page on medical ultrasound history. I do ultrasound as my radiology specialty. The early machines I used were "articulated arm" ones. These used an arm with

I can't believe nobody makes motors of the right size nowadays? It's not a magical diode motor is it?

On the calibrator ground thread, someone mentioned finding a miswired ground resistor, original from the factory. I thought it would be interesting to let people list the Tektronix factory assembly

On ebay, miss-listed as a manual for a 067-0554-00, this is actually a manual for a 067-0544-00, a calibration plugin for the 647A. www.ebay.com/i/133659054167 I don't know how useful or common this

I'm not presently where I can look at it, but I opened my TM504 a couple of weeks ago while evaluating electrolytics and pass-transistors in my TM for ordering replacements. Fortunately those in the

Christian, Dan is most likely right.about relocating transistors that are too hot where they were originally. I have not looked at the schematic or have this device. It makes sense to do this

Hi Christian, This arrangement should be factory-standard. My TM504 is configured the same way, and Fig. 2 Exploded Parts Diagram (rev B from 1974) shows item 34 (identified as Q22 and Q30) as being

What is the part number of the fan motor? I have a Siemens fan motor from a Tek 7104, so it may be larger than the one from the 2465. It is about 2.6 cm diameter by 5.6 cm in length. It is soldered to
