Congrats Captain Clock!!
This radio represents maturity in radio design and the beginning of the "AA5" (Transformer version) Era. The only difference between this unit and later models is the older pin types. The Octal tubes used in the next year's 5T6, 5T7, 5T8 are electronically the same. Nice condition, but do update the caps.
After losing an old Philco as a kid due to a shorted 5Y3, I have gotten in the habit of putting a 3A 1K PIV Silicon Rectifier between the Xformer HV wires and the plate connections of the Rectifier tube (not necessary for indirect heater type rectifiers like 84, 6AR4, etc.). I can't remember what site I got that idea from but many thanks to the Person that suggested it.
