[@erikdenhouter]

(Sorry Paul, once I need to try something. Remove this if you find it unfitting:) Hi Fran, do you know what shadow banning is ? Some are treated like that for years on your channel, for no reason. I can see my reactions there, but no one else can, including you. I found out after two years. THIS reaction on Paul's channel is the closest I can get to tell you, unless I open another platform account (Twitter, Facebook), which I refuse. Maybe check your e-mail accounts, I wrote to one of them to tell you. Hope to solve this somehow, Erik.

[@erikdenhouter]

Well, no reaction at al. It seems that there are corners build into KZbin that just don't 'exist', but I still found one after being misled for two years. And Fran is in it; I can speak, but no sound is coming trough, I am only allowed to 'watch the Fran community', while there is clearly a text field that says: "Add a public comment...". But as soon as I watch Franlab trough another computer, all my comments there are gone. Weirdly misleading. Thanks Paul, in any way a great channel here :)

[@jackierabbit450]

Hey Fran, I have a slightly older 1945 RCA similar to this with a wood case, I never got around to fixing it, but I didn’t realize you were into tubes! Would you like me to send it to you? It’s yours if you want it... I’m thinning out all of my stuff and need to find homes for certain things, and I would be tickled if you wanted it...

[@davidelliott8016]

Yes please to the alignment procedure, they're always an oppurtunity to learn... and it's an excuse to get another of your excellent videos!

[@kevincozens6837]

Mr. Carlson's experience with tubes and tube equipment really shows. Not many people could look at the tubes and immediately know that they weren't in the right place and then know which ones to expect in the various stages of the radio.

[@hestheMaster]

I always go by a schematic to make sure stuff is where it should be. Here the components were replaced by substituting modern replacements but failed to note where the tubes went and bodged the radio up in a failed alignment. It also helps to take lots of photos before and after of the work while progressing with a shotgun job of component replacing especially around the tubes. Sure way to solder a part to the wrong place.

[@pneumatic00]

There is a subtle, but very important lesson involved here. Imagine how long you could spend troubleshooting that radio with the tubes in the wrong sockets? What would you do, knowing that it had been worked on? Even if you didn't have the back-story, you would see those bright yellow caps underneath and know the set had been worked on. *Once you know that, you have to know there is literally NOTHING you can take for granted*--but again, does that mean you have to check every wire, every solder joint...? I myself have worked on plenty of AA5 radios (mostly the 7-pin tube versions and this was 30+ years ago) but still, there for sure was something odd about the audio out tube and rectifier right next to the tuning cap. I will admit, it didn't jump out at me right away. I *think* I would have tried to get a schematic online which would probably have the tube layout and etc; etc; etc

[@hestheMaster]

@@pneumatic00 Never assume anything! Just because someone worked on a radio and you see new parts in the underside don't assume they replaced a part with the right replacement part. Go over every circuit in the schematic to make sure it is right, make sure parts are where they should be and wired correctly to tube sockets. I give you an example of something I found in a newly acquired radio from 1948. A resistor was going into a solder joint and I wiggled it. It was just loose going through the joint of solder !

It wasn't just DIY customers who would be Phantom Twiddlers, the poorly trained techs would do an I.F. alignment using metal screwdrivers. We always "twiddled" the ferrite cores with plastic trimmers designed for the job.

[@crazymennonite]

Thank you for being so kind to my foolish mistakes on this radio. It was my first radio restoration and I knew the alignment was off from the beginning but didn't want to tackle that so I put it away. I always mark where tubes come from now but I was naive back then. Most radios and schematics show a tube layout but try as I might I could not find one for this.

You have got to feel for the guy who couldn't quite make it happen but you did a great job sorting it Mr Carlson.

[@JerryEricsson]

This takes me back to my days on the farm in the 1950's when I used to watch my father as he overhauled engines to make extra money from the neighbors. He taught me a lot about mechanics, and, of course how to farm. One thing he always drilled in about working with farm equipment was to insure that all the screws and bolts were tight before you began a days work. So, for example, if you were going to mow, you went over the mower with a wrench and screwdriver and tightened everything so it would not work loose as you mowed the fields. When I first began tinkering with radios in the early 1960's after we moved to town and got electric power, I transferred that learning and messed up the radios I worked on by doing the tighten the screws thing after opening up the cabinet. I quickly learned that this advice does not transfer to electronics. I guess it takes a few screw ups, especially if you are working, as I did with no advice from anyone in the know such as is available today with the many how to's available on KZbin.

After a full electronic restoration (done with all the wisdom I was able to collect thanks to people like you, uncle Doug and Brad the guitologist on KZbin) it still has a few mechanical and alignment related issues I'd like to address to get it to full working order again after it spent most of its life forgotten in an attic. It might be a European model but I am absolutely certain you can give me the slight bit more of insight that I need to get this piece of family history back to its former glory.

[@hestheMaster]

RCA model 65X1 from 1948. Tube compliment : 50L6/35Z5/12SA7/12SK7/12SQ7 . From the label that was on the bottom, " For Finest Performance USE ONLY GENUINE RCA RADIO TUBES" I found Mr. Carlson's ability to find tubes put in wrong places fascinating and I hope whomever did that never turned the radio on! But that person did mis-tune the radio and screwed it up! Definitely needs an alignment. Work was only half way finished. It would make sense to put in a polarized plug, switch the "hot" side to the on/off switch, and add a fuse on the hot wire coming into the radio. Make it safe!

Another great video Paul! I look forward to your videos along with Joe Smith’s videos( multimeter robustness testing mostly). You two guys have the best EE chops on KZbin. You both design and build your own test equipment, can just look at the circuit and find the issue with little testing, reverse engineer circuits, you both are very good at mechanical work and engineering also. I was a mechanical engineer/toolmaker/CNC programmer most of my career but always had interest in electronics since I was a kid. Being a gigging guitar player for the past 40 years I dove back into that pool when all the good old techs I trusted started to retire and unfortunately pass away. A lot of books before the internet on the subject and these days videos from guys like you and Joe have gotten me to the point of being the guy in my area that most bring their tube amps to for repairs.

Great fun, as always. Thank you. I am curious to have heard you touching on whether "tubes in the wrong sockets" is generally benign (as here) or whether the owner was lucky not to utterly fry the thing to toast (or have it exhibit unwanted pyrotechnical / ~detrimental~ behaviors :-) ). I was on the side of being surprised no damage was done by it being powered up while massively misconfigured, but i am an utter layman in the field of electronics.

[@pneumatic00]

That's definitely a valid concern. As it turns out....once the rectifier is in the wrong socket, there are no big volts being made, hence there is no "big" power available to fry anything. The more generic lesson is that once you know the set had been worked on (whether by back-story or by observing the new components under the chassis) you know that you cannot assume ANYTHING was done right. Not that you are looking for some reason to trash whomever did the work, but just as far as how many blind alleys you DON'T want to chase down/spend time on.

[@steelcity321pb6]

Yes Paul, I for one would love seeing you do a full alignment on that radio. Over the decades I’ve seen a variety of procedures - some appeared to have been unnecessarily longwinded, and others were direct and to the point. So, my reason for requesting a full alignment is to see your method, or procedure, so I might improve upon what I was taught some forty-eight years ago: that being, having fed a given IF frequency (here in the UK it is usually 470kHz for LW & MW), using a signal generator, and either a scope or VVM for measurement, I begin adjustment with the IF transformer associated with the IF amplifier valve. When the signal is peaked I move over to the IF transformer associated with the frequency changer valve and make adjustments to peak the IF frequency, and maybe move back and forth no more than three times whilst avoiding altering the bandwidth. My procedure for setting the oscillator to correspond with the dial is to feed in a given frequency (usually prescribed on the circuit diagram) to determine how far away it is from the printed frequency numbering on the station dial, and if is off frequency, make adjustment (also usually prescribed on the circuit diagram) so as to chase the frequency in so it peaks when it corresponds with the chosen, or prescribed number, or spot on the dial. That is what I was taught when I was a seventeen year old. It will be interesting to see what you do should our procedures differ. Thank you my friend, Phil.

The same as tuning in timing and dwell on a car by ear and a matchbook to set the points and dial in the carburetor by ear and feel and smell to get it running. Then connect your timing light to fine-tune it and your dwell meter and your five gas analyzer

It would be nice to see comprehensive alignments using all the different methods and equipment. Thanks for a great video!

Gorgeous radio. Wonderful condition.

Nice tips, thanks for share!

Haha...when you first said you could see a problem I though the rectifier tube was in the wrong position next to the tuning capacitor. It was the only correct one! I guess that is a standard layout for an AA5. Nice job as always Paul, cheers 🙂

Your audio is excellent

Yeah, very clear. Must be a cell phone mic :)

Not one transistor or IC chip in it- and yet it works! Amazing technology that glows in the dark!
