[DadsPhilco]

Hello all, 1st post here, what a fantastic resource this site is, thanks in advance for your consideration of my enigma!  I have a radio that looks like a Philco 84b (see attached pic), it has the same tube line up, but it has at least 2 variances relative to the schematic shown at this website for the 84b.  Unfortunately there are no labels on the radio, save a chassis number of 38-4139, but I don't see any radio at this site that looks like it, except for the 84b.  The two known variances relative to the schematic are: the heaters are grounded on my radio tubes, and my power transformer has a total of 9 leads, instead of the 10 shown on the schematic.  If anyone has any insight into what radio I have, and how to get an accurate schematic for it, I'd really appreciate hearing from you!
