Yeah... it's why I'm going to all the trouble of reversing polarity of my 40kV supply. You don't want to use it in reverse for the same reasons not to float your scope to measure power circuits. Too m

I've got a 40kV Glassman 2kW I'm in the middle of converting from positive to negative.

Do you think synthetic motor oil is as good as Kano Microil non gumming instrument oil? I'm getting low on that oil.

Is there anything needed to use a 7A16P in a 7854?

If you go solar PV panels, it would be winter daytime heating and entertaining at the same time :-)

Can you rig a little current to flow through a resistance to be Right where the 5V is made, at its SMPS source. or rectifier and caps, (I have not looked at a 7104 schematic today), and relative to a

Seems likely. Can you rig a little current to flow through a resistance to be mild like 20 milliamps total, then do you have a 6 or 7 digit voltmeter? Probing will show dropping volts along power rail

I was getting some extra 7A26's ready to sell, and came across 7A26 B154366, which is an early one with the familiar aluminum isothermal clamp blocks for transistors in cans. Is that just as good as a

Sounds like a MCP 246x scope!

Cinch card edge connectors with 0.156 or so spacing? I have some of those in widths like 8 10 12 pairs of contacts. Can you rig a card edge to stick out of your racks/boxes?

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 ca

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.

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

I thought he died driving it slowly and rolled to a stop with no impact...

Maybe not directly on pages, but he has mentioned Harlem many times... And that's a place on Manhattan island. It was Ritzy in the twenties, and probably is again now, as well as being very diverse. H

There should be. I'd ask their support people directly and include the full email. Forwarding it should get all of an email. (The bounce notice email) JG

There is a lot of change in mail servers because of all the increased hacking going on the last 15 years. I've had to keep upgrading my mail server to stay away from being black listed. You also can r

I think tekwiki is a great place for STL versions of Tek knobs... but a single URL for Tek knobs in all the world? May not happen...

That aluminum layer is the return path for the electrons hitting it, so the field bunches up there. There are so many ifs it's just wild assed guessing, or SWAG, (scientific wild assed guessing).

Here's a theory: Reflected electrons traveling within a narrow angle from perpendicular to the phosphor/aluminum sputtered surface, are bouncing back and some land and are seen. Some go off course and
