Default Westinghouse RPA 5065 transistor radio schematic needed

Hi everybody.

I just acquired a vintage Westinghouse RPA 5065 transistor radio like the one in picture. The picture does not show mine since I do not have the original paper with it.

I cannot find any schematic on the web for this model of radio, even Sam's Photofacts don't have this type of radio.

Could anybody help me on that?

Thanks.

Whilst a long shot, would you post a picture of the inside of the radio. There were a number of OEM radios which had a common circuit and I have, for example, a Benskins schematic which might do the job. Let's see.

I think you are right.
When I'm home tonight I'll post some detailed pictures of the inside and more...
Thanks so much !

While you are very welcome here, this forum is UK based and most members are from outside North America. These radios were never sold in Britain and few members will have encountered them. You may have more success if you ask for help on one of the US forums.

As Chris says, it's possible that a clone of your radio was sold in the UK under a different brand, but it's a long shot.

I have found that replacing all the electrolytic capacitors usually gets this type of radio working. Mick.

Have a look at the Westinghouse Model H-796P6. The schematic is available from Radiomuseum and on first glance should be typical of the design used.

Hera are 4 pictures of my Westinghouse RPA 5065 radio.
One of the picture shows the chassis number which look like
X3203CO1 or something like that..
One oscillator xformer, 3 IF xformers, 2 audio xformers.
And.. nothing written on any of the electrolytic caps..
I could not find any schematic for it
My next move is to replace the electrolytic caps..

It looks like a typical 6 transistor superhet from around 1970 using silicon transistors.

The 6 transister circuit for pocket sixed radios was pretty much the same and the attached is a good illustration. I have titled it for file purposes only.

Before though you dive in and replace the electrolytics, which don't have a hard time, have you checked DC to the circuit? The in/off switch on such radios is prone to tarnish and so makes no contact. If there is DC, is there any hum by touching the top of the volume control? I don't expect 50Hhz but there should be something. If there is, what happens when you put a screwdriver to the base of the last IF transistor and so on?

Sams didn't provide information for any product that retailed for under $10 USD. Radios of that type were generally give-aways to promote the sale of a more expensive Westinghouse product, fridge, washer etc.
Rumour had it, that there was a small firm in Hong Kong building a radio like it for under $1.00 USD, in quantity, including 006P battery and gift box.
Even back then, it was hard to believe how they could sell it for that little.
