1) If sensitivity of frequency counter is too low adjust to max. channel separation
    (input signal: stereo left 90% + 9%, adjust output on right channel to minimum)
2) RC network serves for damping the IF-filter while adjusting the other one.3) For AM RF adjustments the original frame antenna has to be used!

Brief introduction of the Mains Board
ECO Power
Standby Transformer 5203 provides the LPS supply to control the relay 1210, cutting of the Mains supply to the Mains transformer
during the ECO Power (standby) mode.
The Mains transformer provides the following:
- 5V6_ECO for Low Power Supply
- +A, +A/2 and +B to the Combi board
