Tight, there are only 20 Pye from Ajax radios on the site and only 7 have pictures. Model 53-D is not it, but has s similar chassis, has the power transformer farther forward. Tube lineup is all 6 volt heater filaments, two 6BA6, 6BE6, 6AT6, 6AQ6 and 6X4, those are the two tall tubes in yours. I’ll bet the schematic will come close enough to help you refurbish your Ajax Pye.
