Hello,
Any suggestion on where to get hold of a TECNICO ARISTOCRAT MODEL NUMBER 651 (1947) schematic and service info. Happy to pay for time and effort.

Also, how do you clean the thin plactic sheet that is glued inside the bakelite case that covers the glass dial on this radio. It is quite yellow. Brasso only helped a little. I am thinking of just replacing it with some flexible plastic from a craft shop.

I have no service manuals or circuit diagrams however another visitor may be able to help here, as can the various vintage readio clubs.

As for the plastic dial glass, once they go yellow, that is about it for them. I think it is worth keeping the original because receiver originality is always a hot debate topic and if some collectors know that all of the original parts the radio had are still with it then the price they pay can often be a lot higher.

For the sake of appearance though, yellowed dial glasses should be replaced with clear polycarbonate in the case of a flat dial and in the case of a curved dial you may get away with using overhead projector transparency sheets (available from newsagents) or if it turns out that they are too thin you could try reusing the side of a two litre cordial bottle.

Some collectors do make reproductions of many popular types of these dial glasses but they usually confine their advertising to the vintage radio club they belong to.

Brad,
Thanks for the advice. I will keep the old yellow dial cover as a spare, in case I ever sell the radio. I sold a Kriesler beehive radio last month for $380 on ebay.

I will may try some clear acrylic from a photo frame cut to size. Acrylic has around when this radio was built. If that does not work I will try a transparency sheet.
Regards,
Paul
