Well someone wanted the hum gone as the radio is fitted with Philco branded 6A5G output tubes. The interstage transformer on the bottom chassis has also been changed to a UTC LS-21. A very nice and desirable transformer. I'm going to have to listen to it when restored before anything is changed back to original. I have all the original parts to do so if wanted but this set up may be better than when the radio was new.
