TK,

very interesting remarks...but you are falling prey to your own assumptions.
Where did I state anything about OU ? ...preconceived notion.

But anyway your remarks showed me that you did not perceive  the figures he gave: Input is about 10 Milliwatt.
Yeah, one has to pay attention before jumping to conclusions.

Can all these lit LED`s run by 10 mW ?

The video Description in the linked video reads, "Over-unity energy generator using extreme magnetism with neodymium magnets."
The narrator uses the words "overunity" several times in the video and talks about increasing the overunity ratio. This constitutes a claim, in the English I speak, of overunity performance. You may not be making the claim but the originator of the video certainly is.

The LEDs are not "run" by 10 mW at all, they are flashing very briefly and the peak power during the impulse that makes them flash can be very much more than 10 mW. No measurements of output or input are given that I could find, just some random uninterpretable squiggles on a scope screen. Power is not energy and peak power, especially, is not energy. We actually have no idea what the peak power is that is flashing the LEDs.

Contrast with this:
http://www.youtube.com/watch?v=jGmbN1CzmsQ
The six bright green LEDs are indeed running _continuously_ on filtered DC at a continuous power of.... wait for it....  around 1.3 mW, by actual measurements using an inline ammeter and a parallel voltmeter. I don't show the current reading in that particular video but it is about 100 microAmps of DC current.

How about this one I just did today, showing a 100-to-1 voltage rise from input to output, with current in the output strong enough to heat 3 neons to near-failure?
http://www.youtube.com/watch?v=xiYOaguki6c

Peak power is not energy. Peak power amplification of even hundreds of times over average power is not necessarily overunity.  Voltage is not energy, current is not energy. Only more energy out, than in, over a reasonable time, can be truly overunity, and nobody has demonstrated that with reliability and credibility yet.

@TK
The diode was a 1N978B which is indeed a 51v zener. I found a PDF for Motorola diodes here https://www.westfloridacomponents.com/mm5/graphics/F01/1N5231DRL.pdf
I hooked up the power supply just to see if those neons (HV rectifier and HV regulator each have one) came on and no, they did not. But I did see a little orange glow on the calibrator regulator board from what looked like a Christmas light (neon?), not sure this is a good thing? Looks like the inside of it is getting black...
I am only getting 10.4v instead of 20v at the power supply test point (I should have checked this earlier...), 80v test point was within stated tolerance.
Time to relocate my 'mess' so it doesn't take up the whole dining room table heh heh.
Thanks again! I will try to do as you suggest, I'm pretty green at this kind of testing/repair.

PhiChaser,

The 422 manual that TK provided a PDF link for does not include the complete power supply schematic.  I assume that your scope's supply is the "AC only" version (there was an AC/DC supply for battery operation available as well, possibly only for the later FET versus nuvistor models).

Anyway, here is a link to a site where you can download the "AC only" power supply schematic:

 http://elektrotanya.com/tektronix_422_ac_only_power_supply_1966_sm.pdf/download.html

Just scroll down the page to the "Get Manual"...

Also, what kind of meter do you have for measuring voltages?  Hopefully it is something with a relatively high input impedance...

I'm not a huge fan of elektrotanya although they do have some manuals you can't get elsewhere. They have adware and try to get you to download a reader etc.

But the 40 page AC power supply manual is also available from the TekWIKI site, which is a great resource for all the older Tektronix scopes:

http://w140.com/tek_422_ac_powersupply.pdf

Other manuals too, for later serialnumbers, etc:

TK,

Good to know.

I was having a bit of trouble finding the supply schematic and just grabbed the first one that came up.

Thanks for the links.

Those hand taped layouts and gold plated boards are a works of art...

one must learn current does not run coil at onece.(this topic all about it) but in small motors neo magnets used to upgrade their efficiency not to overunity.

Thanks for the replies and the links guys.
I might have time tonight to delve back into it.
I agree with both of you, these boards are works of art.
It is an AC supply, not one of those harder to find AC/DC or straight DC ones.
I don't have a variac, I only have a (cheap) 5A30V DC bench supply (I haven't even had much of a chance to break it in either).
Any idea on this Christmas light?
(second picture is without power on)

Thanks again,

Nevermind, that is an electron tube and those are supposed to glow (I guess?)...
The search goes on... I need to start tracing wires, I was hoping it wouldn't come to un-soldering things.

Yes, that's a neon, it's supposed to glow, they are used in voltage regulator circuits a lot. The fact that it is blackened generally means it has been working hard, but this is probably normal. But check that the line fuse to the AC supply is the correct value. If the unit blew fuses at some point and someone replaced it with a larger value, that's not good.

It sounded like you have one of the power supply voltages out of tolerance. This should be checked first. The problem may be on the supply side, like a bad capacitor, or it may be something in the circuit it's powering that is drawing too much current and pulling the supply voltage down.

It looks like a lot of the board connecting wires are on socket-pins, they can be pulled without unsoldering. Just note where they go! Take pictures!

When you start in with the soldering iron, I would check the output side of the HV transformer first. Unsolder all the wires on the output that feed to the CW bank and the CRT filament, tape them up so they can't short against anything, Or maybe, find the other ends of the wires, they could be plugins to the respective boards, that would be nice. Then check the transformer for output. If you don't see any, it could be that the transformer is bad (  :-[ ) or that the multivibrator on the input side isn't multivibrating. It's a good idea, I've found, to take pictures as you go, and label wires so that you can get them back where they belong.

A variac is a good investment if you are building an electronics workbench, they are handy for all kinds of things.

Hello whoever, just a quick note.
I've built several pendulums and the couple I have had sitting on my bookshelf will swing to-and-fro for a couple months (at least) on a single battery! I've let those two run down to a motionless state and I can give them a push that will set them swinging again for hours (sometimes). Also they will self start when the temperature goes up (like today when it is 90f ugh...) and go all day long until the temp drops back down again... Neat!
Cheers!

Ah, beauty! I love that particular era of circuit board layout.
It reminds me of analogue circuits, in particular, some of the old valve high quality audio work.
