Smile Pye 49Y19

Hello.
I am looking for the schematic/s and more information about a little radio PYE mod. 49Y19, made in Cambridge, that I am restoring.
I can send some pictures of this radio if you need them.
Best regards from Spain.

Hi,

Welcome to the forum.

Pictures are always helpful in identification of sets, especially those produced for export markets.

Regards,

Thank you for your answer, Brian.
By the moment I cannot send pictures of the little PYE 49Y19 because they are very big for this forum. Anyway these are its valves: UCH42, UAF42, UL41 and UY41.
The power supply: 110-160 V. 200-250 V. A.C. 25-100 Cycles or 110-160 V. 200-250 V. D.C.
The radio works, but weakly on its bands (Medium and Short waves).
Thanks again,Brian.
All the best to you from Spain.
Valentín.

Do you know this set?
Thanks.

I'd guess this is a Pye 49 for an export market - extra shortwave and no long wave.

Ideally, you want the service data for your particular model, the 49y19. However, failing that you could get the Pye 49 data via Paul's email service (link at top right of page) and use that. Probably, the differences are just the band-change switching arrangements and coils.

It would be better to find the exact service data, but in restoring radios we often have to make do with what we can get rather than what we would like to get.

Presumably the lower arrowed part has been forced out of the upper yellowish cylinder? They look very much like parts of a wax/paper capacitor that has gone bang. From the position (close to the AC supply switch) I wonder if it was a mains decoupling component- if it was, the fact that it is now open circuit(!) would not have any dramatic effect on operation- a bit more noise or buzzing sounds perhaps.

Any replacement should be properly rated for connection to the mains!

Hello again my friends.
Thank you for your help.
I do not have the original schematics of this radio, 49Y19. but I have obtained that for the related series PYE 49.
I think also that it is a wax-paper empty capacitor but, is it electrolytic? (red band around, positive?).
Best regards.
Valentín.

I would agree with Chris. It is C24 0.01uF mains by-pass. You need to replace this with an X2 rated capacitor which is designed to operate at AC mains voltages...Peter

It's not an electrolytic. Do NOT use one in this position!! It's a paper type but you will have to use a modern polyester type of the X2 class as already stated. Some old wax capacitors had a red band marked at one end to show which lead was connected to the outer foil. This was important for some RF and filter applications.
