Hello everyone,
Many years ago I became the keeper of my grandmothers old TV/radio/phono console set. It worked when I tried it in the mid 80's. I have a friend whose really into restoring old tube radios and TV's and he started drooling the minute he first saw it. Over Christmas we moved it over to his shop and he's started to take a closer look at it. It appears we have a real treasure on our hands. It's 1949 vintage, chassis MV71A, and we can't find any schematics that go back that far, as supposedly Magnavox entered the TV market in 1950. Anyone have any suggestions?

Sir Stephen:
I can't confirm the radio/phono aspect compatability bu as far as the TV aspect, therein, me thinks that you might have an old '50ish CMUD471 chassis inside on your hands, very probably respledidly encased within a blonde slimed oak or a my-hog-annie cabinet with stick legs on the bottom.
Recesssed within the cabinet tops rear, find the the sets secret aux controls and the storage niche for a Red Ryder super decoder ring.

Lifting up its dress and peeking in the rear should reveal a pair of 8 inch Jensen speakers behind that grass cloth front grille.

Its picture tube being a 21ATP4..and make a spot check on the tubes utilized on your chassis and confirm that there are 6SN7's used for the vert and hoz osc's, the vert output being a 6S4, the hoz out tube is a 6CU6, damper is a 6AX4 hi voltage rectum-fire is 1B3.
Whilst 7 pin miniature tubes are being used thru the RF, IF, Sync, small signal processing portion of the set.

That should be enuff initial info for you to confirm possible set / TV chassis identicality.

I have ALL service info

Standing by for feedback...

Thanks much for the repsonse Edd.

I've discovered after checking with my friend that we had a mixup on the TV chassis vs. the entire console. I'm going to put up a fresh post with the proper info. in it. Hope this will help.
