Re: DC504 counter display
You could look to see which other instruments Tektronix used part number 150-1018-00 in to widen your selection of parts mules. Also, you can reverse engineer the pinout from either the schematic

Re: DC504 counter display
Tnx to the group for the suggestions on my DC504 display. I swapped one display digit with another & the problem followed the swap. So, the consensus of the group that it was a display problem was

Sorry for taking a while to get back to you on this. It seems it is time for me to add an S-6 manual to my binder of sampling stuff. Here is why I do not believe the blow-by matters in this

Re: What use for a 640 Ohm 1x Probe?
I should have been more specific. Actually I get about 9.3 MOhms on the 10x probe I checked. I am learning a lot though by thinking about this probe, reading everyone's comments and reading the

Re: Type M01 'scope
I picked up the M01 scope and took it over to the VintageTEK museum for a closer look. It turns out that before the 7000 series got its name Tek developed two products called the L01 and the M01. The

Re: TroubleShooting Some TM500 gear.
I have plenty of TM500 cards for sale as kits, but I will also sell a card set, no connector, to make a plug with, no wires, shipped in a flat envelope for $13.

Re: Tek 422 HV power supply issues
Hi Paul -- Check the resistors in the series string where the focus & intensity pots live. Your voltages aren't that far off the mark. Per the schematic, 'normal' should be a bias of around -45 V. If

Tek 422 HV power supply issues
So I'm looking at this 422 and the trace doesn't get visible until the intensity control is around 3 o'clock. Blanking is adjusted, so that's not the problem This doesn't seem right, so I dug out the

Re: Now: 50 Ohm attenuator Re: What use for a 640 Ohm 1x Probe?
OK, I think I've decided on building a unit inside a little box that can be switched between 1x, 10x, and 100x. I assume I'd just put the resistors in an "L" pattern totaling 50, 500, and 5,000 ohms?
