A man wanted to bring his Philco 49-1611 over to have me take a look at it ! When over-viewing the schematic first, before he made a 2 hour trip in one direction, it appears the radio has Selenium rectifiers , which normally go bad, or so I'm told ! How will changing them out with "equal value" diodes, from our local Radio Shack store effect the voltages in the set , I was told b+ will be higher, but how much higher ? I don't want to experiment with dropping resisters , in a set 2 hours away, for the next service round, if the set fails again ! It's not fair to anyone, maybe best leave it alone, and not repair his radio !
Thanks for your help, Lee Petrie Joilet, IL.

You'd need the chassis and speaker, and do a recap job. It'd be on your bench for a month unless you have a lot of experience and a fully stocked stash of parts.
Enjoy.
