I managed to break the tan tube socket for the 6J8G convertor tube on this radio while I was replacing a resistor. The socket is the only tan colored socket on this radio, the others are the standard brown wafer sockets. It appears the socket is made of a type of cardboard.  
Can this socket be replaced with a standard bakelite or plastic socket?

Bakelite and ceramic are good. The wafer socket tan or brown are cheep and can be problematic thru breakage or electrical failure.

I am sure there is no reason other than that was what was available.

Just barely pre-war radio. Through the prime of these radios little or no parts were available due to the war effort. Anything to make it work was the order of the day. Take care and BE HEALTHY! Gary

Actually...

the light brown/tan sockets were called "low loss" sockets by Philco.

I've broken my share over the years - they are quite flimsy - and you may replace with any octal socket that will fit the hole.

>>low loss...

Not the loss of the sockets, was it? It is then "high loss".
