My dad sold Frantz oil filters (held a roll of TP as the filter media) back in the 70's as a side gig to his teaching job and those things worked great. He had an old Ford 352 engine with over 300K

So, I'm currently in the middle of a lab build-out in my basement and it includes an anti-parallax angled shelf for my oscilloscope and other instruments. It's 60 degrees off the wall which is, now

One easy approach to isolate the bad section of the amp is to short like parts on opposite sides of the vertical amp.Take a jumper wire & short the transistor cans to each other.If the trace centers

SO, Brad, Your Dad was wrong about the toilet paper bearing shim, but “ correct “ about the t.p. oil filter ! This is a true story; I saw, in 1969 , a man replacing the roll of t.p. in

Hello Jeff, Bill, I don't have any experience myself with the 475, nor have one to confirm my assumptions, but by looking at the schematics of the Z axis/Unblank amplifier and to the DC restorer

At an estate sale last year me and another guy came across some weird canisters that turned out to be aftermarket oil filters that used TP as filter elements.  I was told they were used as secondary

I got a request to look at the 2467 and 7000 series blue filter & shield replacements... If someone has these items on hand and can measure them I can look at nesting them into the batch. thx Ancel

Bring along an APRS Radio and we can track him in real time !! That's assuming he has an Amateur Radio License. Failing that, how about a GPS Tracking device. 73, Dick,

The important question is, what will be the disposition of his oscilloscopes if he is not found?

That is my understanding. It has a greater and necessary effect on freezing point and prevention of corrosion. Specific heat capacity is reduced by about 20% so increased flow rates are required for

I've seen everyone's responses to this point and figured I'd add mine. I know there's no advice that would get you to not take that vehicle on this trip so I'm not going to try. I know if I was going

Hi Jeff, I know that the grid bias adjustment is working fine as it moves the cathode of cr1373 from about 80v to 128v. There is no other indication of a problem except that beam-finder blanks the

The fan will start as soon as the inverter is operating but operation will be quiet because the scope is cool and doesn't need much air flow.  No don't recycle power, wait about 30 seconds or so

Great news!!  I would be interested in buying two blue filters for my 2465's.  Perhaps three.  The ones I use now are pretty good but their lineage was claimed to be "new old stock".  So a
