I'm cleaning out two side by side bakelite blocks in my Philco 610. Both blocks have 4989DG inscribed on the side, so you'd think they'd be the same mfd. Looking at the schematic from Nostalgia Air, the part numbers 15 and 36 list these as 4989DG, but 15 is twin .09 and 36 is twin .1

Looking at the bakelite block list on Philoc Repair bench I see the Universal 4989DG @ .1 , but the 4989 @ .09 is listed with different letters, ie. 4989B, 4989C, or 4989G... which is correct, or does it matter?
