Well i'm at it again. You radio guys and gals must think all I do all day is sit in the workshop and fix up old useless radios!

It's not so, its just that I am hyperactive!

Any way, I bought this thing last year and have written up a story about how I made it work again.
Somebody may be able to tell me what model it is and point me to a circuit diagram.

Read and laugh at how I get into technical trouble through ignorance once more.

Cheers, Fred.

Philips Model 131 Radio

I believe it's a model 123, though that may only apply to the all-electric version. If the model number does turn out to be different I will update the details.

A battery set, that would have been a horrible surprise.

The thing looks like a standard Mullard in every way, except it is Philips. (not rebadged)

For the filaments you could have used one or two D batteries in parallel, this would have been simpler and no hum.

I notice it has a shortwave band. Does it work?

I believe it could be a model 131.

Kevin Chant does have the service manual for it:

The Mullard version is the model MBS1112:

It is, indeed. Links updated.

Hi folks, thanks Brad, Robbbert, Monochrome for the above work on identifications.
You are all dead right that's what it is a 131. I downloaded the circuit and also read a bit more about Philips radios.

Robbbert I fired it up again and noted the shortwave does not work at all but I wont try and find out why.
The selector switch has degrading wafers that are buckled so I don't want to move it again.
Probably there are contacts not making somewhere. I noted on another Philips set the same thing with the wafer switches.
The material used and the thickness of the wafers is substandard, with entropy taking over and the material just disintergrating.

I found that a single "D" NiCad which has a natural range of 1.0 to 1.6 volt worked like a charm for the filament supply.
A 1.5 volt float circuit on that cell would probably be a solution for a "battery eliminator".
One other thing I may try is grabbing one of those "supercapacitors" next time i'm in Jaycar. A couple of Farads may do the trick nicely.

Thanks again all for the ID work.
