Paul, Thanks for being so prolific while I am house-bound. I know the time and effort required to produce good-quality YT videos, and yours are the best.
I wanted to say how much I enjoy watching your videos. I appreciate the way you explain things, share your knowledge and experience working with different components over the years. I studied electronics back in my college days and have spent almost 40 years in the IT business. Thank you.
Mr Carlson my hobbys are painting pictures and lisining to shortwave and ssb iam thinking about getting my ham license I have 4 shortwave receivers and Iam thinking about getting Tecsun Pl 660 mw lw fm air SW ssb 6 bands
Why would any one want to put a thumbs down on this guy. He is so good at what he does and he is willing to explain what he is doing to whatever level of expertise you are trained or knowledge you at. I have never seen a video I have not liked or gained knowledge from. Keep it up.
One more of Mr Carlson's video to enjoy and learn. I hope one day, Mr. Carlson take on a The Fisher 80T hi fi preamp and AM/FM tuner and also a The Fisher 80T amp. I've got both from the person who restored and aligned them. He made a great job. But it's never too much to know more about your favorite equipment.
I loved Pioneer equipment, all I have left of my old Pioneer equipment is the PL50 turntable I purchased in Vietnam. I used to have a Hitach AM/FM/Cassette recorder/player combo but some prick stole it when I went home for the birth of my son in 71. Best damn radio I ever had.
Used to have one of these....love the magic eye gimmick ;) restoring a pair of Marantz monoblock amps found in Dad's garage while clearing it out for sale tubes light up so far ;)
Way back in the 60s I used to repair a lot of PA amplifiers, many of which used EL84 tubes (6BQ5) in class B push-pull. Those wax capacitors were terrible as you say and when they leaked onto the control grids of these tubes it would often write off the mains transformer as well. There was a problem with the tubes themselves though. Most were Mullard, a usually good make, but the EL84s used mica separators for the electrodes and the mica would gradually break down and cause the same problems as the capacitors, but in this case caused a leak between the screen grid and the control. The solution, after a great deal of experimentation, was to replace the Mullards with a Japanese make, Pinnacle, which used ceramic separators. I have no clue who actually made Pinnacles (maybe someone here can enlighten me!). Solved that problem completely!
Mr Carlson you are positioned to answer this question better than most electronic engineers: simply speaking , “ how are they (receivers) all different from each other”? What does one brand use in its design that other brands do not? Could also be asked “wherein does the quality lie”?
After watching one of your extended play videos wherein you repaired an amp, I was excited to watch this video. Fascinating suff. All receiver, not face time. All receiver, not snowflake sound effects. Not a made for tv reality show. I love high end receivers. There's nothing better than super loud music with no distortion. Audiophile vs Van Halen. My ears are still ringing.
I have a Pioneer/Allied SM-G204 that is similar to that one .Mine has been restored and i love it. Sits right beside My SX-1980 . Love the old pioneers
I love this reciver, those caps often go dry ,become dried sludge and the Japanese stuff from the 60's are so well roll crimped that they dont leak very often. Very well made stuff. Please restore this tuner,Don't cast it to pile .I was so happy at the end to hear it will be saved.
Very nice Pioneer receiver. Pioneer has always been one of my favorite electronics brands over the years. The best "bang-for-the-buck" there is IMHO. I previously owned many Pioneer car stereo systems, and I still have 2 Pioneer surround sound receivers (and speakers) , as well as a Pioneer turntable. I have never had a Pioneer product fail....ever. Yes, there are more expensive "designer" electronics brands, and even better sounding systems, but for the price Pioneer cannot be beat.
Before multiplex stereo came out around 1961, the only way you could get broadcast stereo was via similcast. Some stations broadcast on two AM stations--one for left channel and one for right, or one station channel would broadcast on FM, the other on AM. To get it to work you had to run both tuners at the same time. The separation would have sounded incredible! Thanks for making another great video!
My father was a HAM an loved stereo systems, Reel to Reel, and my childhood was filled with this awesome electronics, I remember too the smell of this components and fenol boards, solder etc.. Lovely memories.
Omg. When I was a child my uncles friend had this exact receiver as well as a bunch of hi-fi audio stuff from the mid- late 60's in his living room. Thank You for posting this Mr. Carlson.
A special thing about Mr. Carlson's Lab, almost everything I have watched, except for your inventions and other test equipment, are older than me. I'm not young. I enjoy seeing how you transform a rats nest of wires and components into a nice logical layout. My very earliest years, I do recall my father working on a TV with tubes, and taking several tubes to Thrifty's to test and buy a replacement or two, but that's about it. These radios "belong" to our grandparents. They are fascinating and it's good to know they can still be serviced. I would like to see an evolution of electronics, documentary/special, where you cover the design and components of the earliest radios to modern times. What technology will likely last the longest?
thanks for sharing what you ave learnt its great to learn new things . the front of that unit reminds me a little of a classic 60 ty's American car , just a really cool look , thank you !!
That's an awesome receiver Paul. I work on a lot of audio equipment and I think that is the earliest Pioneer stereo reciever that I've seen. Very cool. Thanks for sharing it!
i love this channel. and i show all your videos. I still have 2 tube radios that I still have to repair. and only through this channel do I dare to compare. this is usually very easy to do. Greetings from Germany 👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍
First, Sir, even though I only understand about 5% of what you do, I still so enjoy watching your extraordinary teaching manner. Second, as a mechanic who has restored many different machines, I am always thrilled when I can find an unmolested original condition machine. I expect you are too.
My brother in law had one of these SM-Q140s purchased around 1967 (it was a showroom demo), with a deep blue enamel in place of the black. With a set of Rectalinear lll Highboy speakers it sounded fantastic. I now have those speakers and they are used every day with my Kenwood KR-A5520 receiver. I had to replace the output transistors & main audio power supply filter capacitors for the Kenwood. I ordered the filter capacitors from China. I needed only two so I ordered four of the filter capacitors, as usual. One of the four "new" capacitors was an open circuit, which is why I "over order" from Chinese suppliers.
Just want to thank you for being there with these videos while so many of us are stuck at home. You are really fulfilling our electronics geek needs.with all you know about electronics I'm surprised you're not Dr. Carlson at this point!
This is awesome. I found this exact receiver at an antique store a couple of years ago. Very little information out there. It didn't sound the best but everything worked well and it looks like new. I listened to it for a couple of days haven't powered it on since. I'm anxious to see the restoration and to hear your opinion of the sound when you get it sorted.
I love vintage radios. And I'm new to your Channel. Now, I will say that my knowledge of electronics and radio repair, could be fit on the head of a pin, and still have room left over. Nevertheless, I love watching this channel and I love your videos. And I always learn something new. Learning what transistors, capacitors, and reflectors are etc. I know your doing your video's for those "in the know". But don't forget us newbie's too. And try to explain the function of these components are. Keep the video's coming Mr. Carlson.
I mean... I’ve seen your leakage detector before in your other videos, but it would’ve been awesome to see what the forecast was on the one that did pass. Mainly just re-show is all “new and old” how it works. That and I love how you explain things. Keep up the great work, stay well and have yourself a great day. And thank you so much for your content.
Interesting. I have a H. H. Scott AM-FM stereo tuner that is similar to this receiver. It has the separate AM and FM tuners for simulcast stereo, but it is also decodes FM multiplex for true FM stereo. This tuner hit the market just as FM multiplex was coming into use, H. H. Scott being one of the pioneers in this technology. H. H. Scott also sold standalone FM multiplex decoders for use with older FM tuners.
Good evening Mister ... Beautiful item !!! wonderful construction and very cleaver about the distribution of differrents parts !!! In this difficults times god bless you Mister !!! Eric from France
It is a pleasure to watch your videos as I seem to learn something new each time regardless of the content. I suspect that you field this question quite often but it would be a great addition to your commentary if you could offer a story as to how you come to possess some of this equipment. Frankly, it wouldn't matter if it was the truth or fiction as such stories would simply add a touch of magic to the fabled aura of the Carlson Lab.
I have a friend who owns a Fisher tuner from 1958 similar to this one.Separate FM and AM tuners.Awesome sensitivity in both tuners.Still works but FM is Mono.However, came from factory with a connection in the rear of the chassis to add a Mutiplex FM Stereo tuner in development still at that time.
Oh boy a Pioneer SM-B201! It's in fantastic shape! Very worthy of a rebuild by Paul Carlson! In early days of stereo a radio station would send a signal to both an AM and FM frequency using two separate towers. One channel was on AM and the other was on FM hence you would get a stereophonic effect. This was expensive for them to do this and was a very short lived idea. I love anything with "magic eye" tubes BTW!!! Look up Fisher 800-B to see a the competitions version of this kind of receiver The Fisher 800-B had 22 tubes to do what the Pioneer did. But it also supported true multiplex stereo FM of today!
Get real its useless garbage today , who the heck still listens to am or fm on serious terms .. One side fm one side am, it’s gimmicky at best 😂 Nobody
What a nostalgic receiver.... ! Continue with the restoration, please 🙏 (Can be a 22 hours clip, if you want... we have a lot of "confined" time... 😂🤣😂 in this locked down season.... ) 👋😀
Wow.. didn't know they did tubes but I got into audio in 70s. Stereo Review subscription for decades. Julian Hirsch sent me 😁 Julian Hirsch (1922 - November 24, 2003) was an electrical engineer and audio critic.
What a absolutely beautiful and well made piece of equipment, I have owned vintage equipment most of my life but I have never seen this receiver made by Pioneer. Thanks for sharing.
I understand about 25% of what Pauls' talking about, however his soothing voice is a comfort during the zombie apocalypse we are currently dealing with.
I repaired one of these a while back (not exactly the same model, but the same concept). It was a first for me and probably the only one available in the whole of Portugal :) The idea was to achieve pseudo-stereo by transmitting on FM and on AM simultaneously. There were apparently about 100 stations in the US that used this for a while. The video is here, if you‘re interested. th-cam.com/video/XnJ-QkIMWhA/w-d-xo.html
@Dave Micolichek They sounded awful. I had an old TV Console that had one of this kind of receiver in it and I did not sound good. For some reason I thought it was two FM stations that had to be tuned in on separate dials. This was before FM Stereo Multiplexing
There was a nearly similar trick with stereo records, some of the forst (appears I invented a combination of first+worst LOL) were recorded with one channel by vertical motion and the othe by horizontal... the channels didn't sound equal, so the whole contraption was turned by 45 degrees and now both channels have a slanted motion.... vertical motion of stylus corresponds to L+R and horizontal to L-R. Current stereo FM is also a sum-separation process.
@@AERVBlog There were two of the original dual station stereo systems. The FM+AM system that this receiver seems to be designed to use, and there were occasional broadcasts in stereo with a TV station and an FM station. At least in the later case both channels were FM, but the TV audio subcarrier is narrower than the main FM channel, so it still wasn't equal. Not to mention that you probably had a pair of 4" speakers in the TV and a decent hifi speaker or speaker system in the FM side.
I remember my father mentioning those simulcasts; a lot of stations simulcast AM and FM broadcasts in those days anyway, so putting the left channel on one and right on the other didn't take much extra effort. Technically, it would have made more sense to broadcast the sum on FM and the difference (which doesn't need the same fidelity) on AM, but that would have required one more mode on a receiver like this and made it impossible for people to listen in stereo using 2 separate radios.
Well done Mr. Carlson, those 2 green power tubes remind me of that 1938 Radio you did. Suzuki use to Mfg. Capacitors, guess they wanted to be like Yamaha. Very much like that capacitor tester.
You were the inspiration for me to get back into electronics (from my youth) and built my own lab. It has just snowballed from there. What a fantastic hobby.

Paul,
Thanks for being so prolific while I am house-bound. I know the time and effort required to produce good-quality YT videos, and yours are the best.
Dear Paul, great receiver. My parents had a Grundig Majestic multi-band radio/phonograph. And it had a green magic-eye tube in the front. Great find!
@@ianbutler1983 I concur!
That magic eyes are special and nice
I used to own a Sherwood S-3000 FM Tuner. Great find - two magic eyes!

You were the inspiration for me to get back into electronics (from my youth) and built my own lab. It has just snowballed from there. What a fantastic hobby.
God ! Could you imagine Mr Carlson refurbishing your precious receiver?
