I am trying to troubleshoot a 47-1230 radio. I have a copy of a manual of some sorts for it but I have a couple questions if anyone out there can help it would be appreiated. I am fairly new at troubleshooting old electronics so I hope my questions arent to dumb, but here goes. First, I was hoping someone might have a better manual or schematic than what I have. The one I have doest show how much voltage the transformers should put out. Also, in the Section 2 troublshooting it says to use a signal generator and use an output that is required for each step but I find no where that it tells me what it should be set to for these steps. Third, the instructions say to check voltages in section one and that they use a meter that is 20,000 ohms per volt, if I use my Fluke meter will it give me the correct voltage or is that a special meter they had long ago? Thanks for anyones help and if they have any and all info(a better manual etc) I would be very appreciative if I could get a copy. Thanks, Warren

Here is the complete manual for the 47-1230, but it is in DjVu format and you will have to download a free viewer to see it.

A 20000 ohms per volt meter has a lower input resistance on the lower ranges which will result in lower voltage readings than a DVM like a Fluke. So your measurements with the DVM may result in slightly higher voltage readings than those obtained from the schematic. Don't take exact voltage readings too seriously as they can be subject to significant variations due to component tolerances.

When ever I start a Philco, and I have done many, I go straight to the source for good service information. Our own Chuck's site and order the service package for your radio. It will include great clear schematics and all necessary alignment and change information. Don't start a project without it.
PS: I'm not related to Chuck.

Thank You, Mondale and Codefox for the info, but that is what I already have...Doesn't seem complete in some areas. But I do thank you for your time. Also, thanks for the 20,000ohms per volts info too,. Sounds like I can use the Fluke but it doesnt need to be exact voltages. Jerryhawthorne, sounds like I should order the info from your suggestion. Do you know if it has more info than the stuff I have as shown above? Sounds like it does. I will order and see how it goes from there. Thanks to all for your time and effort helping me with this. This is my Fathers old Radio he bought new, unfortunately it was in a fire i nmy house and I want to restore it. I am working on the cabinet and it looks like it also needs some electronics work also. He is getting old now (90) and I would like to finish before anything happens...guess I better get busy Thanks again for everyones help.

Warren, I too have an 47-1230 - this is a beast to recap. It will take time, but the radio is worth it.

When I got mine, I bought the service manual for it (got lucky and found it on ebay for next to nothing) which I scanned. Very useful.

There are things that even the official Philco documentation don't cover, such as the 3-legged feedtrough capacitor seen here:
http://www.philcoradio.com/tech/ftcap.htm
so don't be shy to ask any questions, people here should be able to help.

Also, please post pictures of your progress.

Thanks Marsupial, I will probably need help at different times through this. I am planning on ordering the service pack from the philcorepairbench that jerryhaythorn suggested. Do you think that is the same as you have or just as good? If not did you want to sell a copy of yours? Thanks again for all the help, I will post some pictures of how it is now, I have already done some work on the cabinet so it won't show the original condtion it was in but I will take a few pics of it and the radio part to show what im up against. With work the way it is I am hoping I have the time to get things done soon on it and keep up with the posts here consistently. Warren

PhilcoRepairBench is either the same as I have, or better. I don't know the amount of data he has on the 1230. Regardless, he also supply the schematics (same as in any documentation) in bigger size. That in itself can be quite useful.


If you have any issues, don't be shy to ask. Here was very helpful in bringing my radio to working condition.

And included is the record changer service manual as well for all Philco radio-phono combos and Production Change Notes if there were any issued for a particular model.

Chuck's site the best. So far I know it is a self-liquidating hobby at very best. You will get the best. Indepedent, not associated,... and so on.

Hey Warren,

I don't know how proficient you are at radio restoration, but I learned a lot of the basics at Phil's old radios at www.antiqueradio.org. On You Tube, the videos of joernone are extremely helpful. His videos are geared especially towards the beginner. Right now he's doing an Atwater Kent. He'll take a radio that looks horrible and turn it into something beautiful. Good luck with your restoration.

Thanks Tom, I will check out the link you offered. I need all the info I can get. Here is a few pics of my Radio I am restoring. It made it through a house fire and I have started stripping the cabinet. The electronics you can still see alot of the smoke from the fire that is baked on. Any suggestions or tips is greatly appreciated.

I am a little worried about the heat the electronics took in the fire, hopefully it will only need the normal caps and resistors replaced.
I will send pics as I progress if anyone is interested.

Thanks for looking at the Radio.

The bottom really does not look too bad, It seems to be blackening from smoke more than anything else. The vinyl insulation on the wiring does not appear to be melted and even the wax paper caps do not seem to be dripping wax, which they usually do if overheated.

I think if you do a normal restoration you should be fine.

[Warren]

Thanks Mondial, that makes me feel a little better about it. Hopefully it will work out easily.

A tri sodium phosphate mix with hot water works well for cleaning a chassis, about a tablespoon in a gallon of water should do it unless it's really grungy then you may need to make a stronger mix. I pull all of the tubes out, and remove the dial if there is one attached, then pour the mixture over the chassis, then scrub around with a toothbrush. Then I leave it for about five minutes, scrubs some more, then rinse with clean hot water at least twice. If it's still grungy I go over it again with the TSP bath, then rise again. I don't immerse the chassis It's more like giving it a shower rather then a bath.
I know this goes against what people think about water and electricity but I do this on a hot day then let it dry for at least several days afterward before trying to power it up. If I have to do it on a cold day, like in the winter, I leave it in a warm dry place with lots of air circulation like near a heat register.
