Dear Paul, I have a Radio Shack Micronta FET VOM from the 1970s. I like the high input impedance, but I regret that they didn't provide a MOSFET version. But, the next meter I would like to have is a VTVM. There is nothing like that classic old equipment smell that the tube equipment have, as well as the high quality performance that I remember from back in school in the 1970s.

[@scottisnotfromhere6553]

I love watching you Mr. Carlson. My dad died in 2016, leaving me with his old Grundig 2220 that he had owned since before I was born. He found it in a dumpster and got it working again. I loved listening to it, I used it for hours and hours. Unfortunately it's full of old caps. I stopped using it because I'm afraid of destroying the tubes. :( I'm working up the courage to replace them myself by watching your videos. My dad had bought an old All American 5 type AM radio before he died and I practiced cap replacement on it. It works! It's pretty out of tune. I don't know if he screwdrivered it or if a previous owner did. One day I'll get the Grundig safe to use again and I'll remember my dad fondly.

[@peterfitzpatrick7032]

Doing stuff like this keeps that connection (no pun intended🙄) with your father... my dad was a cabinetmaker & though I ended up being a machinist all my life, I took up woodworking as an homage to him... I found that I would think alot about how he might do a certain cut or joint etc .. Good luck with the re-cap, Paul here will keep you steered in the right direction... I'm betting yer late dad would have loved these videos we are blessed to have ourselves... Thank you Mr. Carlson for that... From the Emerald Isle 😎👍☘️🍺

[@ianbutler1983]

Manny, Tubes are cheap and easy to replace. The danger is that the caps are leaky (beginning to pass DC) and load down the power transformer until it burns out the very fine secondary winding. There is only a couple of things that usually make a tube radio beyond reasonable repair and they are the transformers, both the power and the IF transformers. Good luck with your dad's radio. It is not too hard to do, but you might want to practice on a radio you don't care about.

[@jlucasound]

Don't rush it, Manny. Do your research. Your Dad would expect nothing less. You will get it right.

[@mannys9130]

@@peterfitzpatrick7032 Nice that you do some woodworking to remember your dad. :) I find myself asking the same "what would dad have done" question and thinking about how I'll approach a project. I recently replaced my water heater. My dad was not a plumber, just a general repairman and maintenance tech for a jail and before that, an apartment complex. He did do lots of plumbing work as a result though. In planning the water heater replacement, I decided "Dad would do this job the right (hard) way using all soldered Type L copper pipe. He'd replace the old shutoff valve and he'd replace the drain valve with a full port ball valve for maintenance." So, that's exactly what I did. I used a few old copper elbows in the system in addition to the new ones from Home Depot. I used his pipe cutter, emery cloth, pipe wrench, channel locks, and work light to do the work. I'm quite proud of that install. :) I feel it's as good (likely better) than work a professional master plumber would do. Deburred every joint ID and OD. Lead-free silver bearing solder. Lead-free ball valve (tricky to solder). Water soluble flux. I practiced soldering correctly for days on some cheaper Type M pipe and couplings until I was very proud of my joints. I could hear my dad in my mind saying "No snots Manny! I don't like snots. Just take your time and let the solder wick in. There you, beautiful! Good job!" I think if he was here to see it, he'd pinch my cheek and say "You're my son." He was only 56, cigarettes caused bladder cancer. I wish I had 20 more years with him. :'( My grandparents were 83 and 81 when they died of natural causes. He could have done 76, I think. He was a good man. I would not be the mechanical nerd that I am today without his love and teachings. Your dad would be happy and very proud seeing you sharpen that chisel and use that table saw. Hopefully you have some of his own tools to use today? :) And yes, my dad would have absolutely LOVED Mr. Carlson. My dad had an associates degree and was a field electrician, but Mr. Carlson seems like an electrical engineer with extensive electrical theory education and advanced circuitry design knowledge. I think my dad likely would have went that same path if he had invested more in his college journey rather than stopping short and going with field work for new structure wiring and service calls. :)

[@mannys9130]

@@ianbutler1983 Thank you so much for this information! You just taught me several things! I do have spare tubes for the radio as well as a speaker and (I believe) a button set that my dad had acquired at flea markets and antique electronic supply shops, but I do not have any transformers. :( I don't want to burn these ones out. It sounds like I made the right choice by boxing the radio up and stoping my frequent use of it until I get it sorted out. I did practice this a bit by replacing the capacitors in my dad's newly acquired Emerson AM-only All American 5 type radio. I found it in his apartment while clearing it out. He did not have it before he got the cancer diagnosis a few months prior to his death, so I had no attachment to it like I do with the Grundig. I think he bought it to restore it as a sort of busy project to stay in good spirits and revisit his youth and old hobbies. He just never got started on it, or he may have just replaced a tube to fix it. It worked ok when I found it. I believe I did ok with that Emerson re-cap. I only replaced the cylindrical yellow and orange paper electrolytic caps that Paul always harps on about being failed at this point in time. What does he call them? Yellow bees, or honey bees, or yellow jackets, or super bees or yellow drops...something like that. 🤷🏻‍♂️ I didn't replace any caps that looked different than that, so I don't think I accidently put an electrolytic in place of any mica or other special, high stability capacitor design. I looked at and recorded every Farad and voltage value that was written on every cap and I remember that I researched the tolerance allowed for these electrolytics in tube radios. Then I searched for the right ones with the exact values or a value as close as possible within that tolerance on online electronic supply shops. I verified that each one's value and position was correct on the schematic as I removed the old ones and soldered in the new caps one by one. I did not take the risk reorganizing things or tidying up all the components like Mr. Carlson often does to make it neat and visually appealing. Just point to point, following the old layout exactly. 😸 When I turned it on for the first time afterward, it worked! I was happy! The reception is not very good though. Only the strongest local station is really able to be listened to adequately. If I remember correctly, the dial was off quite a bit, it had several birdies and hums, and I think one other issue that just made it uncomfortable and annoying to listen to anything other than the station which is very close to the house and has a powerful antenna array. The reason why I didn't power through and tackle the Grundig re-cap after that apparent success was that it functions in AM, FM, 2 shortwave band ranges, and external input mode. There are TONS of components inside that chassis. Tons! They're buried underneath each other and sprawled out everywhere! Very intimidating and I'll absolutely cry if I ruin it. I should probably revisit that Emerson and get it perfect. Maybe add filtering or try to tune it better for clear reception and get the dial accurate. The antenna is intact so it's internal issues plaguing the performance. :( Anyway, thank you so much for taking the time to read my comment and offer your valuable information. I sincerely appreciate it Ian.

Paul, you are amazing. I personally love older products. They can do most things as with modern equipment, but they have one thing the new stuff doesn’t have, and that’s personality, design, and style. I’m a model train restorer, collector and operator, and the older trains have that same type of character. I enjoy watching how you bring old tube equipment back to life again. It’s such a joy to see you talk about the designs and engineering aspects of old electronic equipment, and watching it function again like the day of rolled off of the assembly line. Great work!!

Doubt if many people under 50 know much about vacuum tubes. My first color 25" TV had some vacuum tubes. I built a tube & transistor tester to locate a bad tube in it. Still have my RCA tube Manuel that I purchased in late 1960 's. Have a 5 tube AM FM radio in my garage that still works. I bought it for $10 over 50 years ago. Great vid.

As soon as I saw the VOLTS-MILS across the top of the meter I knew there had to be a connection to Hickok. The font is exactly the same on my Hickok 209A with the black background and white lettering on the meter. I acquired my 209A when I bought out a TV-Radio shop at least 40 years ago, that had been in business since the 1930s. I liked it then because of the uniqueness of the very large meter, now since I've developed macular degeneration the size is a great asset. Mine needs restoration but it does still work albeit rather crochety much like it's 70 something owner...

[@jassenjj]

The tube in the probe is EAA91 and is equivalent to 6AL5 and yes, I don't know a person who is into vacuum tube electronics not capable of recognizing the type of the tube, the tube itself or even the brand just by looking at it :) This particular tube is one of my favorite devices that I've ever seen, it looks really cute in a TV set being so tiny...
