ME TOO!!! As the Popular Electronics article wrote all the way back in 1966: What's next? Colpittsillators and Marconios??? ;-) Tom AE5I

Hi Andy- I hope you wind up liking your 7633 as much as I do mine..... It's the one that I keep on the bench as a "first call" for anything that doesn't require something that it can't do. I find the

I would throw 'em out. I've seen too many of them short and cause a bunch of collateral damage. In my shop they are dumpster fodder..... Tom

Soon as I figure out how to send you a photo I'll get it on the way!

I'm sorry that I don't remember if I got them on ebay or just some website, but a year or two ago I bought a couple of "game console" service extender harnesses, that only require that you cut a few t

I bet you're right, Paul.... Didn't think about the pulse having to be sufficient to get across the LED junction. So far I have only done repairs on incandescent strings. So the old axiom raises its h

Hi Jim- No, it was a very old run of romex that was installed long before we bought the house. And you're right, if they had cut it with the switch on, we'd'a known it at the time! <laughing> Tom

Chris, you NEED one! :-) The first time I tried this was many years ago and out of a string of 100 bulbs, it found each of 13 open bulbs! Oh, that that time I was actually using a 1S2 in a 556 mainfra

Hi Paul- These are incandescent but LEDs should work fine too. One nice thing is that the display reacts so quickly, so that when you move the string around you can spot intermittents, even if they're

I've also use a TDR to find where the yard men cut the romex going to our front lamp post as well. Such a useful tool! :-) Tom

Tom, the 1502 is one of the most useful instruments around! I just finished finding the fault in a long string of Christmas lights with mine! :-) Definitely something essential to have around... Tom

Hi Dave- I'm sorry to hear that you're having trouble with that HV XFMR.... I did a lot of testing and evaluation for Bill Schell over the years and I don't remember him every testing a transformer wi

Sorry for the bother....

Hi Stephen- Have you checked for the horizontal non-linearity with the scale illumination switched off? Just a thought.... Good luck! Tom

Probably not a factor in this case, but in some cases we have found that metal film resistors (of the same value/wattage as the original carbon comp resistors) would blow open when exposed to high inr

Hi Jeff- I have no interest whatsoever in the current oscilloscopes, from anybody. You said a mouthful about not expecting the same user experience that you're used to with classic Tektronix analog in

Hi Dennis- Thanks so much for your help! After going over the email that you sent as well as the bounce notifications that I found that came from groups.io, it appears that either (1) there's all of a
