Post by ivanjon Tue Apr 01, 2014 7:56 am

I purchased a Philips radiogram circa 1955 I think the model number is Philips model 177B I have restrung the radio and all is working fine ,actually it has a lovely sound to it very clear but I don't seem to be able to get the record player part to fire up ,although it is humming and when I touch it the humming stops ,I have not taken it out yet but before I do I wondered if there was something simple I am missing . I will then clean up the cabinet then clear gloss varnish polyurethane ,should be a nice piece of furniture when finished , our son has many vinyl records so we are looking forward to playing those too ,any help would be appreciated , I must say my experience in anything electrical is not great
cheers

The cartridge is the the part of the pickup with the record needle at the end of the tone arm.

Hi Bill I have taken a pic of the cartridge but I am not sure it is that I suspect something mechanical is going on as I am getting power to record player and when I touch the needle on the end of the cartridge it is picked up through the speakers ,I just don't seem to be able to get the turntable to turn ,anymore ideas most welcome

That proves that I'm right. When you touch the needle, you are picking upt the noise because your crystal is apparently broken, or, you may have a broken ground wire from either the back of the cartridge,, or, somewhere in the harness where it goes either at the changer, or, to the plug that goes to the radio chassis....
I'd check all the cartridge wiring first.
Please let us know your results..........

If you don't have one yet, a multimeter would be a useful investment. They can be had relatively inexpensively.

Yes, but, that won't check even a good cartridge. In fact, never measure a crystal cartridge with an ohm meter, as it can burn out the cartridge. an average modern meter will put out several volts more than a crystal cartridge can handle.....

You were saying to check the wiring first. That was the sort of thing I was recommending a meter for, as well as radio and other electrical troubleshooting.

I would guess that is to select either a broader stylus such as would be used with 78 rpm records or a narrower stylus to play microgroove 33 1/3 rpm long playing records.

It looks like I guessed right. Here is a manual for the Philips AG1000 turntable used in your unit. There are enough similarities in Dutch and German I can muddle through the stylus explanation.

You ought to try some domestic sources for an owners' or service manual on it. Use the 177B model number.

I have a friend who speaks dutch they should be able to translate ,I have downloaded the whole manual in dutch but the diagrams are what I am interested in really , the reason is that the turntable is just not working so I suspect it is more than a cartridge that I need to do ,not even sure where I would get a cartridge from here in Oz

Well, while doing a few online searches, I found references to your unit and turntable at radiomuseum.com. One entry says that there is a service guide for the set that was published in Australia. You might check Ebay to see if there are any of the inexpensive service library CD-Roms available to you domestically. The manual can help in communicating any specific problems you have with your unit.

I'm not certain but it seems like we are sending Ivan down the "yellow brick road". On the first page of this thread he indicated that rubbing his finger over the stylus gave noise in the speaker. Seems like the cartridge is working at least a little. On the same posting he indicated that the turntable was not rotating.
Is this correct Ivan? Is your first or at least primary problem that no rotation on the turntable?
Regards, Jerry
