Proud Patreon of MCL ! You never cease to amaze me Paul, and I'm sure that goes for anyone who watches your channel. Another one for the couch tonight, awesome. Take care, stay well. Best regards from Holland,

[@DankNoodles420]

How do I contact you to get a quote for a restoration of my dad's Sony home stereo system, it has a bunch of included units, a TA-AV571 amplifier, CDP-CX571, ST-JX661, there is also a tape player unit and another one I don't have with me at the moment.. also the sub boxes have rattle in them too and probably need a restore. They are SS-U571AV. It would make a great video or two I'm sure..

[@johnvaldez8830]

I am on the edge my seat almost shouting, "it's a short in the filament circuit...there's an open wire!" and so on. It's just so much fun and the best part is learning the step by step trouble shooting procedures with the safety tips. Top notch video!

[@MrPatdeeee]

I just stumbled on this channel. Wow what nostalgia. For I started in 1952 at DeVry Institute in Chicago, to learn radio and TV. I loved it and I was hired on by RCA service company; after I graduated from DeVry. I retired from RCA after 33 yrs in 1986. In 1968 RCA opened up 6 training centers around the nation; just after color TV came into being; to teach technicians to install and repair Color TV's; because there was NOT a single training school that did it. One of these centers was in Miami and I became an instructor there. It was awesome. I had NO idea there were people like you, still working on old AM radio's, etc. I am in awe. You, young man, are VERY well "trained" on things I used to teach. WOW! I just cant get over it. WOW. I just turned 88 and indeed you have taken me back many decades. Thank you so much kind Sir. Note: The "J" scenario when soldering, is a life long pet-peeve of mine. I would not do it, nor would I tolerate it. WOW!

[@MrCarlsonsLab]

Thanks for your kind comment Pat. Happy birthday too!

[@rebelba42]

The Person who swapped those foil capacitors definitely knows the outside foil tester and how to mark them with a red dot, that's for sure :) Many thanks Paul, for making this in Lab II. I really enjoyed watching this repair using a mixed of vintage or self invented test gear! Great Video!

[@YonnyHagstar]

Outside foil is no longer marked as it is considered irrelevant except in very high end high gain high fidelity applications.

[@ltdees2362]

Ahhh...never to old to learn...at 70, you have shown me many new troubleshooting techniques...You have a profound natural talent and teaching ability...thank you for your dedication!

Glad you are enjoying Tom. Thanks for your kind feedback too!

[@terieffo8]

At 76 I also have learnt from these videos

[@davemiller6893]

Thank you Mr Carlson for another enthralling video. I enjoyed it very much. And how appropriate that your video be published just today. Sadly I lost my cousin and best friend today as a result of covid 19. He was an old radio ham, 86, and electonics buff, G3OTW. He was my mentor and together we would restore old valve radios in my shack. Sadly the seriousness of this pandemic is brought home with a bang when someone you love is taken. Watching your video brought back so many happy memories of me and Bill and the many, many paper waxies we changed together. Thanks Mr Carlson and 73s to Billy. Stay safe everyone.

[@MrCarlsonsLab]

I'm sorry to read of your loss Dave. I'm glad this video gave you some good memories. Stay well!

[@beachbum9869]

Would live to see the whole alignment. As a tech I loved doing radio alignments. Both transmit and receive. Just loved it. That was a life many years ago. Thank you for letting me relive them through your videos. Stay safe. Stay healthy.

[@TheRadioShop]

Very impressive unit Paul. Also I have to say your trouble shooting thought process is superb ! These are the type of traps that stump many young techs when working behind failed repair attempts. Enjoyed the show.

[@bwithrow011]

I love watching someone in the modern world, using a combo of old school, new school and self made tools to fix old electronics!

[@davidbeard6851]

I never get tired of watching you at work with these investigations and restorations. It's an inspiration! So please let's see the IF and RF re-aligned on this fine old radio. Looking forward to it and I'll bet the dial tracking's a bit off!

[@terriecotham1567]

You have to love old radios as they were all so works's of art and like old car's people took pride in owning them and treated them with respect. One of my first electronic courses we had to build a 5 tube superheterodyne reciver and the instructors would leave bad parts in the binds. You had put ever part and then test each part as well. Those two old teachers had a smiple way of teachers I love it when people like you take the time to help bring those old machines back to life and in the process all so teach anyone who who may like to learn about those units and how to repair them. Thanks for posting

[@MrCarlsonsLab]

Glad you enjoyed Terrie!

[@davekendall4698]

Reminds me of playing with old TVs when I was 10 years old. I love that you keep the old things running and Interesting use of the meter (no cheap DVMs) & (no DAB radio upgrades) just restored to work how they where meant to be. You are a very skilled thank you for making the video.

Thank you Mr Carlson for this video. These big old radios from the thirties and forties have a aura of wonder about them. It was the so called golden age of radio, Wonderful cabinets and often quite complicated dials and component layouts and short wave. When I was a kid my father had a short wave radio and I also built one in the 1960s and listened with wonder at all the overseas stations in umpteen languages.

[@joerogers4227]

Checking into 25 cps or 25 hz AC in today's standard of measurement was first generated at Niagara falls starting in t he 1890's and of course Westinghouse was involved. Since this was a Westinghouse radio I am guessing that Westinghouse company chose to use 25HZ because this frequency AC was well entrenched in Western New York. As late as 1925 a new plant generating 25 HZ ac was built at Niagara Falls.

[@AndyFletcherX31]

Thanks for the explanation, I was wondering where the 25Hz requirement came from

[@joerogers4227]

[@michaelmontgomery5818]

So glad to see you with another vid! We have to get you to a million subs!!

[@StewartMarkley]

Oh yes I would really like to see you align that beautiful radio. I'm new to your channel so haven't seen you do an alignment yet. I built my first radio from an Allied Radio Star Roamer kit back in 1965, it worked as soon as I turned it on. Was so proud of it and myself and still have the beast, my dad used it for years in his garage. I really enjoy all of your videos, seeing you use the Tek 547 scope brings back memories for me where I used one in my electronics class in high school.

[@myradiovideos]

I notice WWV was off a bit, so on your behalf, I called up WWV, National Bureau of standards and had them adjust their master oscillator!!! Now the radio should be OK!!!! :-) No alignment needed!!!

[@StewartMarkley]

Very funny... I visited the NBS back in 1969 when I was a senior in high school and someone I knew his father worked there. They did a seminar on FETs which were pretty new then, very interesting it was.

[@HansDelbruck53]

I love the look of this old radio. Was hoping to see Mr. Carlson tweak the alignment though.

June 1959 ? hmm ... I was born in June, I was already in the 5th grade then. Seems like 100 years ago. They used to make some beautiful things back in the day . Radios weren't just functional, they also made beautiful furniture. People weren't afraid to put forth some actual effort and pride in their work. What the hell happened ? I am absolutely glued to these videos for many reasons. I spend so much time here my wife has become suspicious, ha ha ha . No need for confusion, common sense and a bit of patience will take you a long way. Good work ! Now about that alignment ...

[@bijouxbijouxbijoux]

Again, another very well made and interesting video Paul ! And it's so amazing that this thing features a 25hz compatible power transformer, as I'd love to design a power supply wich could divide that 50hz (here in France) down to 25hz. It could mean less trouble to take care of possible humings in my designs...But maybe try to have some 25hz power transformers designed instead...I need to check your Patreon page to talk to you about this and other stuff :D

[@joerogers4227]

As for getting shocked by B+ voltage while inside of a tube radio. In 1960-61 I was going through USN Basic Electronics school in Millington Tenn. We built a simple superhet radio. Our final was to trouble shoot. I failed because I got shocked by B+, Automatic setback to repeat that 2 week module. Still gradualted in June 1961.

[@jimprice1959]

The reason for the license was that originally BBC and CBC were financed by radio licenses rather than commercials. They actually had roving vans with detection equipment that could sense the oscillators in the radios. They would drive through a neighborhood and cite those who were listening without a license. So the US had free radio financed with commercials and now we have paid cable and streaming. What goes around comes around.

another vote for an alignment video on this one! i'm hoping to find a video of your quality showing the alignment done with just a signal generator and an oscilloscope (which is what i have, no VTVM), (not sure if that's possible at the moment). i have watched your Echophone EC-1 alignment video multiple times, as well as the stewart-warner one and have taken a lot of notes :-) what i am not quite sure of is whether i could hook the oscilloscope up where the VTVM goes when doing the RF alignment (or maybe some other place). thanks so much for your contributions.
