6. PU 1 (Power Chassis, Plug-In Board)
This board can be found together with the transformer and
the PC Board RS 1 in the Power Chassis NE 60.
Apart from the fuses, this board carries the electrolytic
capacitors for filtering the supply voltages (power supply
and amplifier). Furthermore, this board acts as connection
board for the swell pedal (05 3), loudspeaker and relay
board (RS 1).
7. RS 1 (Relay Board)
In the "stand-by" mode (green LED in on/off switch is
illuminated) this board supplies the organ with the BATT
voltage and switches - via the AC line relay -the entire
organ on or off when the on/off switch is depressed.
8. OS 3 (Swell Pedal, Footswitch)
This board has two footswitch connections as well as the
reflex coupler, which supplies a current of 0 (low volume)
to 0.6 mA (high volume), depending on the position of the
swell pedal. This range can be fixed with the potentiometer.
