Westinghouse Radio Desk Set Speaker
I have this Westinghouse radio desk set with telephone amplifier from the early 70s that I recently purchased however the speaker doesn't work. It currently measures 3mega ohm. I have been looking around on the internet this evening for a replacement. I found one at Farnells, it's a 50mm 8ohm unit. The dimensions are right but I just wondered if the 8ohm will be ok. Will this be alright as a replacement? The original has S-54 written on it - see picture.

Re: Westinghouse Radio Desk Set Speaker
If the amp is transformer coupled then it will probably be OK. If the amp is transformerless then the required impedance could be anything.

Re: Westinghouse Radio Desk Set Speaker
Does the Westinghouse unit have a model name or number. I'm becoming quite a serious collector of intercoms, office communication & similar units and many of them use 25 Ohm speakers, some 8 Ohms. One or two have used 50 Ohm.

Re: Westinghouse Radio Desk Set Speaker
WOW! That's a nice unit.
Seeing it now and that it's made in Taiwan, the speaker is most likely 8 Ohms.

Re: Westinghouse Radio Desk Set Speaker
Well the speaker arrived the end of last week and was fitted and the radio works a treat.

There were lots of background noises when I first tried the radio but that turned out to be our internet hub and all the other rubbish that was on at the time. I took it upstairs and it was completely different, I picked up loads of stations and all very loud and clear. The clock was cleaned and oiled, it keeps very good time. I have a little bit of touching up to do on the base and some repairs to the tops of each of the two pens, however saying that it doesn't look like it has had hardly any use. It came in its original box with its literature inside and was even supplied with a little 'ear', one end you stick to the side of your old telephone and the other you stick into the back of the clock radio and you can have your phone as a speaker phone through the radio speaker, and it works. Thanks to everyone who advised on the speaker. Apologies for no photos of the radio side of things as I seem to have deleted them, but I may, once all the touching up has been done, put this in Success Stories and I'll carefully dismantle enough to take some pics (for those who are interested).

p.s: It's good that shielded magnet speakers are still available, the ceramic magnets on later speakers don't fit earlier units (radios, tape players etc) where the pcb was designed to fit around the smaller shielded magnet.
