Tom, I was a Tektronix Field Sakes Engineer in the early 1970s. The product line had matured to the 576 Curve Tracer. I was based in Palo Alto and later Santa Clara. Being smack in the the middle id Silicon Valley I sold hundreds of Curve Tracers to dozens of companies. What a great flashback! I’d used the 570 while temporarily based in Beaverton.
Wow. Stumbled across this video (and Part II) and loved them. I am an amp tech and aspire to get my tube matching capabilities up and running and these two videos filled in a few gaps for me. I have a Tek 577 that's in my queue for a clean up (and to address my aspirations). I haven't fired her up yet. But I also don't have any tube fixtures for it. This video makes me want to lay my hands on a 570 (with all the tube fixtures of course). Anyway, thanks very much for this. I'll be going back through some of your other videos and have subscribed.
That was a good score! Tells us something about what our postmen know about us! Now, what is the chance my postman will step up and sell me a 570? I'll up my chances by hanging a sign on my front door: "Tektronix 570 tracer wanted!"
For your modification, I do hope you used the silver solder in the spool provided inside the 570. Those ceramic terminal strips wont tolerate anything but silver....
thanks for the tour of the 570. never used one but would like to see how it works checking a good versus bad tube.if you can do that on a next video. john
Isn't it a problem to have a 400V/-300V around this 6CL6 which is rated for 300V of plate voltage ? It seem that this tube is used way far from the standard specifications (here according the schematics at 418V of voltage plate as the cathode is at -18V). An other weird detail is that the 400V unregulated supply (rated at +/-5%) is noted 460V in this schematics, which is even worse !

Man, this unit is INCREDIBLY valuable!!!!
Thanks to the UPS guy that brought you back to electronics!
Yay, back to electronics.
Thanks for this video, and especially the positive vibes and encouraging words. Stay safe and healthy!

Very nice instrument, and a good demonstration too. Thanks.
Very nice! Thanks again for showing electronics!
Nice find!
Thanks for sharing this great tester :)

Great video. Thanks .
I envy you. Those things are right-arm material... :)
