:I have a General Electric Musaphonic clock radio. The radio came with no tubes and the labels were also missing. All I can find to indentify the radio is on the inside back cover. It says model 420 and 421, but I can't find any schematics for it. The radio looks like it takes 6 mini tubes. I have no idea which tubes and where to install them in the radio. Any help would be appreciated.
:Thanks.

Hi Steve,
There is a schematic for a GE C421 6-tube clock radio at the Schematic Bank at http://techpreservation.dyndns.org/schematics/General_Electric.htm. This may be what you are looking for. The file is in djvu format.
