  • Notes
  • The Osram valve equivalents are 1A7 1N5 1H5 1C5. Only the N14 (1C5) is different to that used in the standard model ADP2. The bias resistor is also different for the N14 (820R instead of 560R). Frame aerial consists of a MW winding plus a loading coil for LW. Almost identical chassis as in the predecessor ADP1 but in different case. The documentation "Trader Sheet" 883 covers both models.
