To be honest, this video brings me back to the days when I was 14 or 15 years old. Back when I didn't have much fancy equipments except a multimeter, my desk or working space was just like this, not a big area stuffed by electronic scraps I collected from nowhere. The best fun was poking randomly with my old analog multimeter and discovering the circuit part by part. Although sometimes magic smoke would escape and the next thing I know was the circuit went wrong. Very sweet memories, Thanks for sharing it, for real.

Thanks man!

That's a very nice vintage piece of test equipment! Thanks for the "tour". I would say the only downside is sourcing those large batteries for the B+. I have some old portable tube radios that use 45 and 67 volt batteries, which don't seem to be available anymore.

Great detail walking through your processes. Thank you.

100% worked for my old M65 Elite. Thank you.

Turn off auto-focus. Less blur.

Thanks buddy, this worked a treat! Saved my mouse from being thrown in the spare parts box in the shed.

WORK FOR FISHING , IF YOU KNOW HOW TO SET IT UP RIGHT. BUT HIGHLY ILLEGAL . COUNTRY BOY CAN SURVIVE !

Nice switch! Good bargain too, they're pretty expensive usually. I'm late, but nevertheless present.

I bought an SX303r new in the early mid 90's along with matching Pioneer dual tape deck and 6 cd changer. Don't know what happened to the other two, but my daughter has the receiver now and it still sounds as good as the day I bought it. Even better, actually since she's got a pair of Infinity floor standing speakers that sound a lot better than anything I had back then! Its a good amplifier, its got more precise sound reproduction than the 1980's amps, and none of the heavy, muddy sound of the 1970's gear. Enjoy it!

What cartridge does it take on the tone arm?

amazing, it works, thanks !

Hey I just got one of these, and I can’t figure out how to wire up the cards, could you help?

I have a 6 bar phone generator

I have a 6 bar are you interested

Regarding OWON B35T+, when you are in diode mode, and there is a short, does it make a beep noise? I am talking about when it is in diode mode. NOT in continuity Mode with noise. Thanks. Merry Christmas.

I love your vintage test setup. I like to work on old tube amps so I am using also vintage test tools, like an old Hameg scope, Philips signal generator and Philips RC meter

I have an interstellar timer that turns off and on when it is set on “dusk to dawn”. Can it be fixed.

I have one of these ..Didnt realize that the signal meters had backlights!!

This worked for me, mouse works properly now... At least FOR now... One thing I want to add - unless my mouse was just special, it definitely took a little bit of force to get the cover off after taking the screws out, looks like it was glued... Hopefully this is an every 3-6 months thing, and not a "you have to do this twice a week now, and then the more you do it the more often you have to do it... until the mouse just stops working entirely" -- I'll try to post an update on if I have to re-apply it. But it's working perfectly right now!

Thanks Doc. I gotta check my magic eye tube in my pioneer.

It worked ,was about to smash it,only had mouse around 7 months too. Thanks for the info.

Throwing in a comment for good measure. This 100% worked for me. I didn't have contact cleaner so I just used Isopropyl Alcohol on a brush. Brushed the sensor a couple times and clicked it through, repeated a few times. Waited til it dried and BOOM my mouse is back! Thanks so much for the video man!

Strangely, it worked! :)

Hi Doc Brown's Radio Lab, I,m Just starting to try and fixed old Radio, Believe me, Not easy at 62 years old, I have ,Medical Problems,and need to keep Busy, I have alway's wanted to learn, And don't plan on dying any time soon, Anyway, I just bought a old Knight majic eye,Capacitor checker, Could this be converted, into what you have, If I added a step up transformer, with variable capacitor to adjust voltage output, and add a voltage meter in circuit.

Well done! That magneto is military surplus; it came from an army switchboard. I found an old PDF about it by doing a web search on its GN-38 part number. It is army manual TM 11-333. Mine worked much better after disassembly and oiling. Anyone who touches the end of the magneto while turning the crank will get a painful shock, so mounting it to a board is a good idea. As the kids try it, they will discover that the handle is much harder to turn when connected to the lamp. That shows how you can't get electrical energy for free. More load on the magneto makes it harder to turn. I built something similar, but included a wall phone. That lets me show people "on the hook" and "off the hook", and how "hanging up" means that you literally hang the handset on the switch hook.

for some reason my mouse started to move to the top left after that any ideas why?

a good one

Hey Doc, wonder if you have any thoughts on this: I'm doing my first restoration of an old capacitor tester bridge. What I'm finding is that I can't get the thing calibrated so that the eye is open widest across the whole range of values on the dial. In particular the dial reads quite a bit higher than the capacitor value at the high end of the range based on the eye being open wide. BUT if I connect a meter (negative to chassis, positive to positive terminal where one leg of cap is connected) I find that the lowest voltage is pretty close to when the dial is at what i believe the cap value to be, and the lowest voltage is NOT where the eye is open widest. Any thoughts about why that last thing might be the case and what might be done about it? Thanks for any advice!

Could you show the procedure of putting this panel into Walk-Test? I know its related to the dip switches on the back of the board but their is very little info on this panel online.

Classic👌🏻

Is there a way to put it on walk test?

Neato 👍

Hello, good evening. What is the weight of the item?

How can a magnet actuate the smoke detector ?

Do you know if the data logging for current is stored on multimeter would like to use over 24 hour. Want to make sure multimeter stay on logging without leaving my phone next to meter? Dose it take sd card. How long will it log data for.? Thanks

The sx 39000 is my main for my reck room I love the "digital" ish look such an interesting piece to look at and I've become really fond of pioneers "class AB" sound.

Thank you for the video😁

What size screwdriver did you use?

Diodes need to be cut to eliminate the annunciator trouble or you'd need to load the annunciator output but we always cut the diodes when there's no annunciator.

Nice garage sale find. Great explanation. Thanks for taking the time to do it.

Great video

00:59 Nice one

keep making videos!!

Connect it to any landline phone (with bells or electronic ringer) and it will ring. But the phone will not ring if it is off the hook.

Does it have to go ALL the way to the right for it to be good? The very first 5 tubes I tried goes just a little into the good side...🤔 Maybe it needs a little Machine oil on the needle component. Anyone anyone? Lol 😉👍🇨🇦

I should add that even on the supplemental roll chart I can't find reference to 12BE3 and 12BF11 Compactron tubes nor to an RCA 12EX5 "Electron" tube. Any advice would be appreciated.

25 years ago I bought a large box of vacuum tubes and then bought a 10-12 tester to see which are good so that I might sell them. Not knowing anything about electronics your video, and the link to the pdf supplemental roll chart are an amazing help to me and much appreciated.

How does the battery charger work on this?

Hi, really interesting video. I recently bought one T-60 for me as electronics technician, enthusiast and curiosity about electronic tubes cause I'm from transistors era 🤷🏻‍♂️... I wonder where can I find that extra chart you show in you video? I'm from Argentina by the way so I salute you from here Doc. Thanks in advance for the help
