How to repair antique Philco AM tube radio Hum No receive

- Опубліковано 24 тра 2019
- Another old radio with bad filter caps. Just a bunch of noise/hiss/buzz no reception. As usual the filter caps were toasted. I did not spend a bunch of time on the radio. The task was to get it running again for a friend. There is still some good info to reference here. Now you can try the same remedy if your radio is suffering. Another note, my friend Rich, Reel Swede provided a bonus bottle if wine to be featured. Check his channel out if your in to fishing. I always welcome wine donations! If you would like to shoot a short wine fetching video, send me that along with the bottle of choice and I will feature you! Thanks again all for sticking with D-Lab. More cool stuff coming up! TD

No need to ever apologize for anything. Your videos are educational, informative, and fun. Oh, and free! Thanks for the great content.
Thank you my friend
Nice old radio. You should leave that old cap can in there so it looks original. Good work, as always. 🏅
You're a nice guy..not charging someone who would have difficulty paying...kudos to you....please toast yourself with a glass of wine!
Nice repair Terry.
We love your video's, greets from the Netherlands.
Leuk dat er meer nederlanders zijn die Terry volgen :-)
Thumbs up for the wine. A glass of the old vino never hurt anyone. Plus, you know what youre doing. Thanks for sharing
Enjoy your wine! I sure enjoy your videos and my wife enjoys trying to find the same wines that you feature. Keep up the excellent work.
Now there's an advertising slogan: "Will work for Merlot"! :D
For safety reasons I would put a fuse in line in case that 80 plus year old power transformer decides to short one day. Also the Bakelite block across the line cap should be replaced. The other blocks could be rebuilt too for peak performance. I understand that you didn’t want to get too deep into a restore on this but it,s such a nice old radio that it deserves the extra mile.
I always learn something with your vids, Terry. Thanks, man!
Nice radio and a great repair.
I enjoy your videos keep them coming.
I don't see any reason or difference that the wine makes enjoy.
Enjoyable video there Mr. D-lab, and I must say it never fails to amaze & pervade me on how some folks still staunchly uphold Puritan ethics(!) So, even though our world is rapidly changing - in a bad/weird way - socially & financially due to a lung-bursting pathogen, the biggest problem we seem to have, as indicated by many, is a very intelligent Yank electronic tech drinking a glass of wine while he explains his craft! And Jesus wept...
Nice device, nice repair, and I do believe you are a great guy too
Really enjoy watching your videos Terry, normally with a good bottle of red myself. Very educational. Keep up the good work and keep the wine flowing as its all part of the theme. 73 from the UK :)
Hi Terry,
I'm just glad to watch your vids!! Keep it up.
Im not that great at electronic repair-yet- but every vid I watch makes me a little smarter.
Sometimes I go get a glass of wine and drink right along with you.
tuning cap has peeling plating on plates... connect tuning cap across line volt along with 100 watt bulb in series....tune back and fourth and peeled plating burns off
..common problem....take care to isolate cap from circuitry....I learned this trick in 1962, my first radio repair job
Nice thing to do..and I enjoy your laid back style, but always squint when I see you plug in an old radio and fire it up sight unseen...lol. I'm just getting back in to tube radios, it's only been 50 years.....but retired now and I really did not know how much I missed doing this!
d-lab was born in 1962 and i was born in 1963 that means to more old buzzards live on the planet zog .. tnx jeffrey..
Great video, it takes me back to only AM radio. 800AM CKLW Detroit Windsor radio station
Stumbled on your channel just now. Loved this! Liked and Subscribed.
Nice repair and nice radio mr.Tery !
Well your friend has to be happy with that working radio. Good repair
Got a Philco 38-9.It's similar to that one. I have hum very bad. I've replaced the filter caps and all the other caps. Did nit even make a dent in the hum. I measured the hum with a decibel meter and it's over 80! That's hum!
nice radio I have about 2 dozen philcos in my collection and I love the ones from the 1930s
WOW awesome video my friend , the honor was all mine! Thanks for the shout out the winery was very nice!
Hey Terry, about 2 years ago I found a filthy 1939 Philco floor model a the local flea mart, took it home and determined that the radio was useless but the cab could be cleaned and refinished. I stripped out the radio chassis and built a point to point Princeton clone into it. Of the 4 control knobs I used the original volume on off and the tone controls. I used the other 2 holes for pilot and input points. A telecaster jack cup fit perfect and with a new weber 12 inch alnico I now have a gorgeous 15 watt combo amp/jukebox. I did this because I watched your videos and thought that in 1965 as a 15 year old I could build a Heathkit receiver without screwing up then a 68 year old might get it. Thanks for your help, best regards. p.s. the wine name looks French and they may pronounce it like Door Don.
Keep up the wine info Terry, goes well as a Segway in to the repair video. Would be cool if you could do a video on how you built your “Dlab” dummy load device. Nice unit.
Very cool radio and repair. I think it’s cool that you would repair it at no charge.
I’m a small time collector, and on a very tight budget. I have a lot of radios, But not a lot work. I am very slowly learning to work on them. Have no equipment at all, yet.
So I have to “ farm” them out, costing me far more than what many are worth. That’s ok, if I have it. I do have someone who gives me a break on working on my tube radios, but getting anyone to work on my transistor radios is not so easy.
So all of you who work on radios, hey, it’s nice to give a guy a break once in a while.
I’ve seen a few of your shows. Cool.
📻🙂
Cool to stumble across this video. I have this exact same radio sitting around waiting for some attention. It's a little bit rougher shape than this one but i like the design
1:10 - Good for you! I love wine. I'll have to send you some of my Tempranillo.
We want wine.. Thats a part of the presentation, and is nice to be happy..! You are welcome to Slovenia, to try some of our best wine like Refošk (RED) and Malvazija (white).. I bet youl d like those..!
Another cool video! Cheers
I love your style... Brother.
Terrific keep it up....Thank you very much indeed. Sir.
looks like you enjoy red wines so one day ill send you a jug of my home made pinot noir
Awesome video!
keep on the wine and keep your blood flowing terry 73,
Thanks he video Terry!
Do what you want man its your show.
I like the wine. YES!! wine is necessary!!! lots and lots of wine!! YES!!
I would like to add that if you replace a glass tube with a metal type to be sure to verify there are no connections to pin 1 on the socket. On metal types pin 1 is grounded to the casing. Often the mfgr's used an unused pin (1) as a connection point. Grounding that pin can cause the factory smoke to escape from the parts connected to it.
i love these radios
OK Terry, man of many talents, howz 'bout you and the Mrs makes some vino?
Smash the grapes with the feets, those in grown nails, athlete's foot, corns and bunyins add special flavor. Put the grape juice in a 5gal jug, add brewer's yeast, sugar, then use the condom method to ferment. The condom gets big from CO2, the idea is to prevent oxygen from getting into the jug that spoils the juice. When the balloon stop growing, then it's time to bottle and age the wine. Don't forget to wersh your feet, lol. The trick is where to steal the grapes?
Terry first off you are not going to please everyone so do as you like. Your wine is what makes your channel unique. Please put the original can capacitor back in the radio leaving it disconnected. That way there is not a big ugly hole left there. Plus it looks better with it in there. My opinion anyway.
Terry, NOT ENOUGH wine! LOL
Nice old radio
Sound is verry good , thanks
Im from mumbai india
I like teprecorder n radio
Only you know how many empties go to the wheelie bin ;-)
Ok you have inspired me! I'm going to start to 3D Print for Tequila! Need any knobs or display parts? Great video!
I often find the 'buzz' on the AM band is usually coming from a florescent light fixture (in my laundry room...!)
People are "wining" too much ;)
Roger that man
"Sour grapes", I suppose!
Boor-go-nie (the nie is attenuated at the end). The double o is the same as in loop. The go is like the start of « goal ». The nie (gne) where gn stand for Ni but the tongue fall a little from the palate at the end. The final E is pronounced like the u in « drum ».
Geez, the commenters need to stop _wining_ so much about your vids...
I like the dial indicator on this radio though, generated by a slit aperture in the back of the dial plate and the whole thing is lit by one light. Nice piece of engineering there.
Cheers,
Terry,
Drink wine, swallow LSD, smoke opium, whatever you are on is working, you produce great videos!
Thanks,
Ian
Hi terry! Im from argentina. Some day ill find the way to send you some argentinian malbec wine botllels....
On something that old I'd never toss an original can. I'd restuff it, or just disconnect and bypass it. Totally spoils the classic appearance of the chassis, which is a big point for some collectors.
D-lab, Drink your wine if thats your thing bro! Just all things in moderation..... Most of the time anyways.....
You should have never told me you work for wine.... I got a hoard of old stuff.....
I have a Philco 38-12 radio. It doesn't tune in any stations. I've checked the oscillator, it's not open (has close to the correct ohmage per the schematic. The audio section is perfect. I connected a 1000 hz signal generator to the grid cap of the 6A7 tube and heard a faint tone in the speaker. On the 78 tube it's a little bit (but not much) louder (when touched to the grid cap) and on the 75 tube grid cap it's really loud. Not sure if it's a bad tube or bad 110 pF cap or the oscillator itself, or maybe the tuning capacitor. I hope to one day get it fully operational, especially after replacing all of the wax paper capacitors and both electrolytic capacitors.
Great video! I wish you could fix my RCA 56X2 :-) Cheers!
I am kind of surprised you fired up an 80 + year old radio with the original filter cap still in the circuit. That would've been the first thing I would've changed before firing up the radio. If not that, bring it up on a variac to hopefully reform the old electrolytic.
Terry. I don't care if you drink. Just watch those capacitors. LOL
I have a 42-390 console humming but not receiving. I'm praying this helps.
Good info thank you. I am interested in what appears "EF Johnson" on your shirt. Any connection to EF Johnson 2-Way radio co. and connectors and more, that employed hundreds in Waseca MN for over 80 years ? Plus several more manufacturing plants Iowa and Idaho. They made very good products and had a big role in WW II radio products and CB days.
You may want to check the Bakelite block caps.
Working on a Zenith clock radio and have the same issue except I have changed the electros and most all caps, 4 tubes. It's a low hum with no stations.
Fellow Class of 1980 here!
Wine is essential for repair !!!!!!!!!!
Looked up Philco 37-62 radio from 1937 . It is the same radio. They may have made it in 1938 too!
Love Dark Horse wine!
Nice!!
Great video! And yes, I like the occasional glass of red myself. I usually keep it for when I'm editing my videos though! 😁Do you have a relative that does videos on classic volkswagens by the way??
Nice radio, but I wish you had physically left the old cap in so it would look visually correct. But then, I've been known to cut old can caps open on 1920s radios and hide modern caps inside so it still looked original.
those are some damn good friends,,.🍷🍷🍷
hello terry
any advice for some who dont have a tube checker handy.
thanks
john
Hi Terry!! Just found your channel and think you are the coolest guy around! I recently picked up a Philco Transitone Model 27-9944 in completely original condition and am trying to stop the humming/get a radio signal, but haven't been able to find any info (schematics, troubleshooting manuals) online anywhere. Do you know anything or have any resources that could help?? Do I just need to replace all the capacitors? Thanks so much!! Sending red wine delights from NYC.
Cheers!

Good job, I need a list or link of radio lamp faults and their repair, thanks.
I save the straight Scotch out of the bottle for when I'm working on anything made by Apple.
I have a silvertone kicking my ass right now. I've replaced all of the caps and bad tubes but all I'm getting is random buzz and hiss and no stations.
Very nice radio. And, who made that long-reach nut driver?
Ever watch "Radiocruncher" another great beer drinking radio fix channel. Great stuff.
I just got a Philco 48-464 and I wanted to know how to remove the chassis from the case? Thank you!
Did you have those sneaky autotransformer radios in the US?
We had them in Germany, they have a power transformer, often even a 2way rectifier .. but the chassis is hot, since it's an autotransformer, not an isolated one.
Hello Mr. D - lab, you have inspire me to work on some of these old radios. I'm on my 3rd one an have run into an issue. I am working on a Philco model 50-1720. I have given it life but no sound! It still a
has the original antenna with the wires solder to it but I don't know where to hook them to. I have search the web for schematic but had no luck. Could you sale me a schematic on this model if you have one??
When ours don't work, Pa just spits in the back of it and whomps it.
I have an old 1950s GE radio that doesn't pick up on any stations just static any suggestions 😅
Nice
How about mildew in IF coils?
A plague on my bench. Many stored in basements and unheated buildings have this problem.
I’m a 1962 as well :-)
I had an old Siera radio 📻 that I need your help with the thread that turns the channels and adjustments please
I'm restoring an old Sparton Tube radio circa 1946 and ran across something on the schematic that I have never seen before. The last resistor listed says R18 2700 ohms 5. w. w. w.. All the other resistors show the ohm value and watt value as an example R4 100 ohms .5w etc. My question is what does it mean when there are 3 "w" s like that? I went ahead and replaced the R18 with a 2700 ohm 5 watt resistor. The radio works and I have the proper voltages but the resistor is getting extremely hot. Any thoughts, ideas or suggestions would be appreciated.
only comment is I would have left the dead can cap on chassis , the wax caps must go for reliability ect even if test ok as they can start to "leak" electronically as they heat up with the now use after sitting for many decades
Belo rádio da Philco.....
May i ask what you are using to spray on the tuner?
Question, how are you creating that temp antenna?
Use the Dark Horse on that tuning cap. That'll quiet it nicely.
Woo hoo Tennessee! 😬👍
Hi Terry, I don't have a UA-cam channel but I think if I did I would only survive by ignoring the negative comments. In the last 2 vids you have referenced the "hot chassis" issue inherent in AA5 (or 6) radios. Could you do a vid explaining in detail on how to make theses radios safer?
Good morning, I am unable to fix my collection there's no one that have parts?
Merry Christmas D-Lab do you know anybody in the New Orleans,Louisiana area that repairs tube radios
Ive got a issue with a project. Speaker wires to a marconi model 26 were messed with. Its a multi point from the speaker and m scratching my brain. Can you help?
I have the same radio. I just cant figure out how to wire everything together. I got it from a guy who did a bunch of stuff to it and I cant reverse it back to being original.
