I recently came into possession of a Columbia 360 Console. Surprisingly, it works. The Radio is a little shoddy (may need new antenna) as it has a hard time picking up stations. The record player works as well.

I ordered a new needle and have started taking it apart a little to clean it up.

I may replace some wiring.

My big question is where can I get replacement speakers? One kind of works, and the other does not.

Thanks!

DO NOT power this up again until the electrolytic capacitors have been replaced. If they short out, at very least, take out irreplaceable parts, at the very worst, start a fire.

The radio could be affected by bad caps.

Thank you so much. Any idea where I can get replacements and what part #? I looked for them on the diagram and didn't see them.

If I'm not mistaken, the diagram on the back is for the Changer/Amp.
Service manuals for Three versions of the 360 can be found here, thanks to Bill J.

You will have to identify the tuner/radio. Look for chassis tags or inscriptions.

When disconnecting interconnecting cables, label them with masking tape flags or directly with a sharpie.
Example: tuner chassis terminal-A to amp chassis terminal-A
B to B etc.

otherwise you'll get lost when it comes to reassembly... :shock:

A digital camera makes a great aide-mémoire.


Can you solder?
Can you read a schematic?

Thanks a lot.

No
No

Maybe I should take it to a professional. I can do the speakers, but not the other stuff.

I seriously doubt there's anything wrong with the speakers, it's most likely a problem with the amp. Do you have another speaker you can try temporarily? It doesn't matter what size

Amplifier is certainly suspect. But do I see a massive tear in the cone of the speaker in the picture above? That can rattle and sound bad. But it can also be repaired first. Repair is cheap and if that doesn't work, maybe you can then go on a search for a speaker.

And the speakers are Jensen.

It might be the amp, but regardless, it is torn badly.

I am taking it all to a repair shop soon.

Can you post a photo of the rear tube chassis sticker ?

This amplifier has a power transformer and there is a 5Y3
rectifier tube in the photo, along with maybe a 6V6 power tube.

So, this Columbia circuit is not going to be found in the regular Columbia 360
tabletop portable record player schematics.

As suggested, the circuit chasses numbers may be stamped on each of the
radio and amplifier chasses' bodies.
