  • Notes
  • The radio model (Super Inductance) 535 is probably a short name for RA535A but since it is named 535 in a schematic we have to keep this model too to avoid further "bringing in's" over the next years by members reading 535 only.
    Please look up RA535A and place the pictures there. The RA535A (535, 535A) features the same chassis as the Philips 730A and 720A. We believe that the rectifier given in the Schématéque is not an American 80 but a V80 therefore we enter V80.
