I just received a Lyric radio made by Wurlitzer. It is my first old radio and I would like to restore it. It is both am and foreign/shortwave. When I plug it in all I get is a hum through the speaker. I found dthe schematic for my model on your website and it is the 470 with a serial number of 4601154. I know very little about fixing radios but I am adept at learning new skills. Is there any book or web site out there that can help me in troubleshooting and teaching me this skill? Thanks for helping in my pursuit of this endevor. Your thoughts would be much appreaciated.

you are on one of the best websites for learning tube radio repair. for your current radio with a hum,replace electrolytics 1st. pay attention to polarity ,if installed backward you will have lots of smoke. be careful and pay attention to your work and it is actually fairly easy to do this.

Here is your schematic: http://www.nostalgiaair.org/PagesByModel/528/M0016528.pdf

There are at least a dozen or so books on fixing old tube-type radios. RadioDaze sells several.

That set has high voltages that can knock you silly, or worse. My vote for a starter set would be an All-American 5 AC/DC radio.

For the radio in question, the first step is to replace the two electrolytic filter caps, as Phil says. Then see if all the tubes light up, and check the filaments of ones that don't light with an ohmmeter.

If the radio still doesn't work, then I would start by checking voltages compared to the schematic and troubleshoot in a logical, systematic manner.

Once you have the radio working, more or less, I would then replace all the paper capacitors, one at a time, testing the set after each cap is replaced to check for errors.

This all assumes that you have a multimeter, soldering gun, and can read schematics.

Doug, you're too modest. Tim, check out Doug's website at: http://enginova.com/Antique_Radios.htm and get a good idea of where to begin and how to do it.

Thanks for the insight. I look forward to playing around on my radio. I will also be very careful. It is not fun getting shocked. I will check out the web site and books that everyone sugested. It may take me awhile but I look forward to one day telling you all that I was able to fix my radio. Perhaps I may become a radio junkie too. lol, Tim

Doug, Thanks for the imput I also have another old tube radio that has 5 tubes. I can't identify it. Perhaps I should work on it first if I can get a schematic for it. On the front of the radia it has the words "Auburn" written on a metal plate. On the bottom it says "Licensed under Hazeltine and Latour patents and Applications" It is missing the back cover. The speaker says "The Rola Company, Model f series." It has only one band ranging from 55 and ending at 170. Not sure what Band that is. It is a small table top model and I would call it art deco. Can you help.

I forgot to enter the tube numebers. They are as follows. from left to right. 38, R, 39, 36, 39. Thanks for your time. Tim

550 to 1700 KHz is your standard broadcast band. The Hazeltine patent was for the superhertodyne means of building a radio. Those patents expired in the nineteen forties. Those "All American Five" radios almost all have about the same schematis, only a few variations in wiring. I would strongly suggest ficing the AA5 before getting involved in the Wurlitzer. Here's another little piece of advice for your two cents worth: break the radio down into different parts, instead of looking a one whole radio, look at it as a power supply (maybe a 35Z5 tube and a couple of electrolytic capacitors) an audio stage, (maybe a 50L6 and a 12SQ7) an IF stage, an oscillator/mixer. If you get one thing checked out at a time, fixing a radio is really simple and fun. I worked since 1960 on radios and in my retirement, look what I am doing.

Hi Tim, "Bret's Old Radios" offers a 4 DVD set on restoration. They cover electronics, wood and bakelite restoration and much more, each DVD is over 2 hours long. It is like having a friend show you how to restore old sets. They really helped me since I'm new at this also. I read several books and they just went over my head. Now I understand what the books were saying. The set goes for around $60.00 it was the best $60.00 I ever spent. You have to be very careful voltages can be well over 150 volts. You can contact Bret at www.bretsoldradios@att.net Happy Restoring, George.

Thanks for the hint on about Bret's old radios. I ordered the set of dvd's today. Look forward to reviewing them. Tim
