Sir this radio cabinet size complete

Signal generator!

Very interesting...thanks for sharing

Thanks!

That must have been an Good Angel that pushed you away. As we research famous scientists, electricians such as Tesla Edison we realize there are Good angels and Bad Angels. Being shocked feels like an evil entity Force. I would not attempt anything anymore unless I'm standing on a large thick rubber floor mat, gloves using any other cautions.

I wonder how that compares to modern LED searchlights?

You use it to check in with your boss, assuming you work for Ming the Merciless.

All my life been curious with these radio receivers and many other types of equipment I have only just begun to collect but it is so inspiring imagining putting together your own station or recording studio

Can't wait for the restoration to come out. I have a similar piece of equipment (a military linear power supply) that has lots of hughe switches and stuff that I'm not sure how to clean properly. I'd love to see this before I do my restoration.

I didn't get the relay; I got the choke (inductor); I got the varicap/varactor diode; I didn't get the capacitor; I got the four position switch; I got the big wire-wound resistor; didn't get the tubester; I got the big inductor; failed on the capacitor but thought the larger thing was an inductor. I'd say 7 out of 10. And, no. I didn't Google anything.

Perhaps a small mirror to observe any changes on the front display?

A long time ago I bought a Amana Radar Range microwave and I think it had a 10 year warranty. But the touch screen failed in about 5 years and they told me the 10 year warranty would not cover the touch screen. So I took my money and bought an Atachi microwave model number MR 5240 with mechanical knobs. I got it back in 1986 and it is still working today. That's 38 years that I have had no trouble with it. And it cost me $125.00 back then brand new,,,,,,,,,,,,,,,

You forgot to mention when use dmm for 20,000 ohms per volt need to use shunt resistor to simulate a vom

I added line cal pot to my hickok 600 put it under a socket so can adjust like your b&k calibration adjustment. Very handy to not have to raise tester up on blocks or flip it over to adjust a vr

I replaced my hickok 752 with diodes makes tester more accurate cause both sides balanced

I stopped the video at 31 seconds so I haven’t seen what it is . I think it’s some type of radar or sonar?

I used to pick up radios and console pieces RCA recording studio chairs a lot of stuff so easy but now it's scarce

Can I send you a 1930s radio to redo the guts

Paul another great video, I knew this looked familiar and I believe I have a couple of these that I picked up after visiting Purdue University's salvage buildings daily for 3 decades before working at TRW automotive in the late 70s, 80's, 90's and 2000's. I learned of their salvage while attending Purdue from 1975-1979. I am retired now and am going through many hundreds of electronic and laboratory items that I picked up for a few bucks at a time, I have alot of Textronics, HP ect.. items as the university used these alot in their labs. Your videos are allways fun to watch and to learn from.

Very coo!

Very similar to the Pearless Magnarc Light we used with a Simplex 35 cinema projector. That thing had a 3 phase power supply that used large mercury rectifiers I do not recall how many watts it consumed but probably more than 1 KW. Quite a contraption but it was bright and got the job done although it took a bit of skill to keep the carbon rod advancing system correctly adjusted.

First guess before watching is, wait for it... A mini cement mixer and a troth with some kind of planar on it????? lol

I suspect the CRT is a replacement for a smaller CRT that probably would have had some kind of plate with metrics around it instead of a rubber liner. -edit: its also a little odd to see rotary switch stacks that are different colors. You've got the pretty standard brown for several, then just one that's white. Those switches can be a bit terminal for restorations if they've been damaged enough.

Sounds like a marine radio lol

Hello mr very serious electronics engineer, I HAVE 1 QUESTION, and i can explain first what it is for, it is a high efficiency 48v to 120vx2 inverter based on egs002 and chinese mosfets. I am looking for a transformer with higher efficiecny, so I am looking at amorphous toridal transformers. They are not on the market for diyers, they would have to be custom ordered, BUT there is a prewound transformer for a welding machine with maybe the right specifications. Is a zx7-400 transformer good enough for the bridge inverter? Are the turn ratios close enough? WILL IT WORK? Efficiently... The one I am looking at is 38:4... Can i center tap the 120v just by adding a tap there at the middle of 38 turns? I guess All i am asking is only 4 turns or 5ish turns at the input good enough for the inverter board, switching and boosting the voltage right. It seems like its going to cause quite and electrical clack. I cant imagine well the emf transferring well to load, but I suppose that is what they are meant to do, low impedace primary. COULD this egs002 24 tube inverter board work well with the premade zx7-400 (428) trasnformer, amorphous??? It requires a damper choke but I can do that one...

Thank you

Way to show off a bunch of crusty old electronics.

I like the color of the side panel.

9:19 Wow, the idea of building something that can't be mended isn't a new one! 2:54 that looks like a replacement headphone socket. Some early headphone sockets were 6mm, not 1/4 inch, and when 6.3mm became so common, lots of sockets didn't fit. This was a pain in the 1960s and '70s

Really good video. cheers

I'm going with version one flux capacitor. All of them.

Discovery unit for a high altitude spy plane.

Hi Mr Carlson, this is one of your best videos I watched to (several times). A tremendous job (sound, video, edition, technical tests)! I however have a question: you said the best result were with *red* LEDs. This seems strange as cadmium sulfide LDRs have a sensitivity spectrum centered on green. How do you explain that? Is it because HP LDRs use a different or proprietary technology? Or is it because red LEDs have a better efficiency than other colors, with better light flux?

Great work I am 77 years old and i building a VTTC and using a GU 81-M I have never played with tube in my life so I am learning something thank to you .Regards Roger Mission BC.

We learned the schematic symbol as Pointing iN and Not Pointing iN, to distinguish them.

God bless the guy who invented circuit boards.

ham radio

I don't know what brand it is but it's an oscilloscope

You dam sure know what that scope is...some of us take offence from BS....

Please keep on full restores #2 is my vote On a feedback I would like to see a Hallicrafters SX-100 or SX-71 ,SX-28 more people have these than a more obscure receiver just a thought.

I'm pretty sure it's a navigational device. The dial is for tuning a receiver, which no doubt, is fed by a phased antenna array. The CRT screen displays a line in the X-Y plane, the orientation of which indicates the direction of the beacon that's tuned in. It's certainly for use on a boat or ship, as indicated by its weight. Aircraft electronic equipment is lighter, as typified by the "ARC" transmitters & receivers, and the good old BC-348.

7:39 That switch is an "interlock." It disconnects the power AND shorts out the filter cap(s). All broadcast transmitters have them, along with a "grounding stick," a hooked conductor connected to a grounded cable, with a long, insulated handle. It's laid on the HV terminal of the P.S. capacitor. When you're dealing with MANY kilovolts, you don't take chances.

"P F" cannot mean "picofarad." That unit of capacitance came into use fairly recently, around the 1960s (my choice of words dates ME!). THAT device is from the age of black crackle paint & black Bakelite knobs, WWII or pre-War. And a "picofarad" was a "micro-microfarad," or "uuF."

It is certainly an egg candling light, 25VA at 6.5 Volt = 3.8W so a suitable 3.5 to 4 Watt 6V (ac or dc) lamp will be safe. I have a 1940's Speed Graphic (press) camera with flash attachment, even a few flash bulbs.

Like a radio of certain type...

@15:38 you made me giggle. I love that smell as well. 😂

That high voltage relay is interesting, what year was that made? Worked with vacuum breakers in the 15KV range, but were only open and closed. Guessed the choke, diode, switch, resistor (worked with larger ones than you showed), and second choke, I thought those were AB resistors, got me.

The second one the choke is the only one I got, but I love the new format idea. Did the silver band on the inductor near the end mean anything telltale! Vague memories of things I repaired in the 70s and haven't seen since.
