After several posts on the BC-348 and modifications, I have a question.  I have a 

BC-348-C made by RCA and has another tag, "modified by Belmont, BC-348-S".

From what I can determine the modification was done to add the LF band.  Was

anything else done?  Haven't been able to determine what all it entailed.

It has been further modified to include an AC power supply and an added

meter, "S"?  Came from engineering lab at state university.

Just curious. Any help?

I also have a BC-348-P by Stromberg-Carlson.  It is complete with H/B

built in power supply.   Both will be put on my auction soon.
