Beomaster 8000: Reassembly...Where do all the wires go?

I think it is best to remove all of the Beomaster boards and parts to work on them. It is easier to work on the components individually and not worry about accidentally damaging a nearby component. It also allows the empty cabinet to be inspected and cleaned.

Reassembly of all the removed parts can be a daunting task. Fortunately I have done this enough times and have plenty of photos of where everything goes.

The next sequence of photos show the reassembly of the Beomaster starting with the (almost) empty cabinet.






















First I add in the left and right output amplifier board assemblies. These are the assemblies I have already bench tested. To reassemble them in the cabinet I had to remove the transistors (and PTC) from the heatsink and then connect them back up. I am so glad I am using the sil-pads.




















The power supply board and regulators are next.






















Then the FM and FM Interface boards.






















Followed by the preamplifier board.






















Before continuing with the microcomputer board I added some of the interconnect cables.
Now the microcomputer board.




Time for the display board.























The Filter and Tone Control board.























Here is everything installed in the Beomaster cabinet again.
Tomorrow this receiver should move from the work bench to the test bench.
