  • Notes
  • The assembly wiring is for two channels with each having 4 chassis: 245 unit, powerpack and two 250 units. We are not sure if the rectifiers are UX281 and if there are two for each 250 unit as shown in p.an C-9036, Rider's 4-13 for the 1070 amplifier. It seems that the model 1070 amplifier is the 250 unit shown in the assembly wiring.
