221 is a Philco run number. Also one tube should be 1LA6 not two 1LN5's.

:I require a schematic for a Philco model 221 radio. The radio contains tube: (1)1LN5, (1)1LH4, (1)1LN5 (2)1A5GT/G and has a 460kc IF. I am trying to restore the radio, build a power supply for the radio and to get the right wiring configuration. Any information on this radio would be of great help and I would be very thankful.
