Behold!

I’m somewhat confused by all the talk about the fan. I found mine loose. I tightened it a little and it works fine. Further, Why not just blow the dust off with air Again, Again, I did and had no

I thought that might be in order but wasn't sure if just removing the screws would free the back panel enough (due to connections, etc.). I'll give that a whirl. Odd that the manual doesn't mention

Didn't someone post a drawing from which one could machine one of these collets a year or three ago?

Loosen the screws that hold the rear panel on and you should be able to withdraw the power supply. Regards

I disassembled this frame from a 7A16. It will come with the 8 corner screws that turn it into a box, the back plastic end piece, the front casting, top and bottom rails, no side covers, (but those

Tapped lightly on the shaft, the collet released, and the impeller came right off. The collet is indeed broken. That's quite fragile (as stated) as I don't recall putting very much torque on that

Oh, disregard that, I am remembering just a couple days after when the whole thing was not done yet, and the report did not mention any cause of death.

Hi Chuck- I really do understand! I guess it all depends on what the project is. I wouldn't let my 7104 or 7934 go any quicker than the 555. Just a matter of using the 555 for what it can do (just

The report in the same mag he wrote for was accurate.

Hi Greg, I must be remembering incorrectly. I did a search, and came to the same conclusion as you did. When I was a child, my grandfather died of a heart attack while driving, towing a trailer. He

Jason, you are so right about the tunnel diode based trigger systems in some of the analog scopes. There's nothing else like them. Plus, with a digital scope, the instrument is assessing the waveform

It is a plastic collet, in a plastic taper. The two practically weld together after being under tension for many, many years. The screw is molded into the plastic collet, and turning the screw

Thanks for your info! I also love old stuff and I have couple older scopes - if one call them that. Simpson Handiscope - it is working! Sencore P5 148 with service manual, but non working for now. I'm

Thanks for the info!

Searching for Tektronix "impeller" vs. "fan", I finally found a picture of the collet: https://qservice.tv/vpasp/shopexd.asp?id=4199 That makes sense to me now. Still unsure how turning the screw
