Spent the evening installing ICs on the RF board. Ran into another set of NE602 ICs (Double balance Mixer/Oscillators) that were replaced by SA612AN chips. The replacement chips were not mentioned in the manual or Errata sheet for the manual. This was not a problem since the replacement could be confirmed by searching the internet.
One of the steps included mounting the MC1350 Surface Mount IF amplifier IC. The Surface Mount IC came already soldered to the PC board as shown. Connector pins were supplied to mount the Surface mount PC board to the main RF board.
