    I think I have a vary rare radio phonograph as I can not find a single thing about it on the net,
    It is a Royalmont model 8312 serial 0612 made in MT. Royal Que.
    It works but with a hum from the speakers. If anyone has any information on this or can point me to some websites with info,
    it would be appreciated.

    The biggest problem is its Canadian and I find available info is a little scarce for most Canadian only products. It is Marconi brand and Royalmont is the model name, I am sure there will be a schematic available. The other problem is up until very recently radio/record players of this units vintage were not considered at all collectable. I could dig around and see if I have a schematic if you like.

    A schematic would be great if you have one, is there a way to tell the year it was made?

    I will have a look Ray and get back to you. Looking at the tube types it is post war for sure, most likely early to mid fifties.

    I think I disagree with Greg that Royalmont is the model name. I think it might have been built by Marconi or under license from Marconi, but sold by Royalmont as a Royalmont product. The Royalmont model # would be 8312. It would be a stroke of luck if the Marconi and Royalmont model numbers were the same.

    This is what I first thought as well, but I dont know a lot about the old tube stuff.
    I noticed some numbers on the metal chassis as well one set is 889 and a second set 28 5 64 im thinking this second set of numbers is manufacture date?

    Thanks for the photos Ray.
    I could not find any schematics for the radio. If it was mine I would change the capacitors, clean the volume and tone controls and it should work , although it might need an alignment after the caps have been changed.
    The hum you are getting probably is because the electrolytic caps are bad.
    It looks like the values of the caps are on the caps. Just make sure the polarity of the electrolytic caps is proper.

    Thanks to the fine fellows over at SQCRA – Société Québécoise de Collectionneurs de Radios Anciens
    I now have the schematics for my unit.

    Does the schematic say who it is that made it or whose name it was sold under?

    The schematic page is marked “MARCONI 633”
