Crosley Model 5M3 Reception
12/12/2002 8:25:10 PMBill
When I got the 5M3 from this elder lady, she told me it worked. In fact she listened to it from time to time even tho the cloth cord showed some bare spots. I took it home and in the kitchen the wife and I plugged it in and it did play very good and picked up lots of stations. My son and wife came in the house about same time and heard it play and me bragg over it. The volume was loud enough for me. I "know" there was not an antenna wire connected!

The set had all original parts except one tube wasn't a Crosley. Anyway I thought it best to get all new capacitors and replace a few of the resistors and new power cord. I got some help doing this plus even got better tubes. My problem? Can't get stations or any sound unless I hook the set to my shortwave long wire antenna. All very clear and louder than I recall the first time in kitchen. I have tried various lengths of antenna wire up to 15 feet and nothing. What is wrong? What have I done to deserve this? I don't want to use my shortwave antenna as it is not in the house proper. Appreciate help.

Hi Bill

Check replaced parts against the schematic. Be sure values are correct and parts not connected to wrong pins.

Changing certain caps can effect alignment. You may need to peak up alignment?

Thanks Norm,
I've went over and over the schematic and the best I can tell I got everything connected right. Now I did use 22MF 430 volts for the filter caps. I didn't have the smaller value in the right voltage. Didn't think that would matter. Would it? I've begun to doubt myself about it playing without antenna. If I was mistaken before about no antenna, blame it on my age maybe. But my norm is to keep all parts taken off a radio together. I don't have wire in my box. Regardless it still shouldn't take much antenna wire to bring in the stations you think? I want to avoid fooling with the alignment if I can. Thanks again.

Hi Bill

Slightly larger filter caps will reduce hum but not cause a proplem. Using 10-20 feet of wire will work for an antenna.

Did you try the radio at a different location in your home the first time? A radio higher, near a phone or TV antenna may operate louder without an antenna. In a basement reception won't be very good.

Hi Norm,
Got to confess, it happens to the worst of us. I just couldn't give up on my problem. So I checked my parts for about the hundredth time and then it jumped out at me. R22 is a 275 ohm resistor in the cathode circuit of the 6D6 oscillator and creates the bias for the input section. I thought I put in a 300 ohm. Not so, it was a 30 ohm! Not only that, but R23 was so far out of whack I won't admit to it. Corrections made and this old Crosley is working fine on six feet of antenna. Loud enough too. Tho longer length does increase the volume and pulls in more stations.
