Canada Beomaster 8000: The display board is ready

The display board out of the Beomaster 8000 from Canada is completed now. It was the final piece before starting the functional testing phase of the restoration project. Once this board is installed back in the Beomaster I will recheck the power supply voltages and the output amplifier assemblies.

After installing new smd LED devices in the segmented display assemblies and bench testing them I sealed the display modules back up and checked them one more time on the bench.

They look much nicer now that no stray light is able to get out.

Before I installed the segmented displays onto the display board I changed out the four indicator lamps on the board with four Beolover LED indicator assemblies. The change to the Beolover LED indicator assemblies requires the removal of four 220Ω resistors on the display board (R34, R36, R38 & R40). They are highlighted in the picture.

Now the display board can be reassembled for installation back in the Beomaster.
