This assembly drawing shows a summary
of all possible versions.
For components used in a specific version
‘see schematic diagram respectively partslist.
ED marked components to be assembled
as service solution for Local/DX - switching
Use service test program. By selecting the TUNER TEST test frequencies will be stored as preset frequencies automatically.
Vit 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 !
4) MW has to be aligned before LW.
