Can find no identifying marks. Stamped into the back of the chassis is'849501 Made in USA'. 10 tubes on the chassis, 6AG5, 12AT7, 6BA6 - 2, 6AU6 - 2, 6AL5, 6SQ7, 6V6, 5Y3. Also mounted in the cabinet is a 6E5 with no connecting wiring. Any help would be appreciated.

I just clicked on the links to the pictures and they dont work. At the top of each category page on here is a tutorial on how to post pictures using the picture viewer used on this forum. It might be of some help if you cant repair the link's that you provided.

Looks like a real barn find. I can't tell what it is though.

Smacks of Magnavox... Looks like a 25hz. power transformer too. No probs. on 60hz...

Had a similar Magnavox chassis a while ago, hummed and needed work but it could still blast away. Played it in the backyard.

IMHO, fix it by gut instinct.

It appears to be a Stewart Warner, model 9151 is close.

Well its got Modern FM on it which means it can't be any older than 1946 and with the tube lineup you say it has where it has a mixture of octal and Noval tubes its probably no later than 1956-57 as around 1958 they started doing away with octal tubes all together in favor of an all noval tube design in radios because they were smaller tubes and put out less heat than the octal tubes especially for the smaller tabletop radios, the bigger consoles like the Magnavox Concert Grands and Imperials still used octal tubes up until around 1960 when they finally went over to an all noval tube design for their stereos.

As for a maker it looks like it could be a Motorola as Motorola made a radio very similar to that in design in the early to mid 1950s, as for the power supply its looks like a regular 60 hz power transformer to me, as it looks just like the power transformer in my 1941 Fada Radio I have which was designed to run off of 110 volts 60 hz AC, and I think by the 1950s they had started standardizing household current to 60 hz and started doing away with the oddball household current designs like 40hz, 50hz, 25hz, 16hz 133hz (at least in America, the majority of countries around the world who use 220-240v AC use 50hz AC whereas countries like the US and Japan and parts of China (Taiwan, Hong Kong, Malaysia etc), Mexico, Canada, and parts of Central and South America which use 110-125 Volts use 60 hz AC.

Just my 2 cents worth.
