A few years back, I bought a BeoMaster 8000, along with the SC80, a BeoGram and a BeoCord. I was super excited, as it was a well-working system. I had to have it shipped, though, and the BeoMaster was damaged in shipping. Luckily, I had insisted on insurance! Either way, I am a curious lad and I pulled the unit apart and started digging around to figure out why it would not work. In the end, I determined that the power supply board had been cracked and damaged when the transformer had come loose from its moorings as some idiot backed a forklift into the shipping box (or whatever happened).
One of various helpless threads I started at that time can be found here. After I repaired the broken board and fixed the other idiotic issues I had introduced, the system worked for a year or so before it died with a bad cap on the power supply board. This was a sad day, as not only had I grown to love the old girl, my wife had taken a shine to her as well. eBay kindly provided a nice little BeoMaster 3000-2 to handle audio duties while I gathered my wits (and a few capacitors) about me.
Imagine how proud I was when I re-capped the PSU board and both output amps and everything worked! Right before I put it all back together again, though, I plugged it in to double-check everything and shorted something out on the LH output amp board (I can't remember what, but the thread should provide details.
I finally got that fixed, and everything was fine except for the memory functions, which seemed to be fully inoperative (see thread here. We used it happily for a while, but eventually took it out of service due to an issue that I can't fully remember. However, what I do remember was that moving or fiddling with the power supply board would cause the relays to click and channels to drop out, etc, leaving me with the theory that the PSU board was the source of my issues.
I recently found a cheap 8000 with cosmetic and other issues on Craigslist, and I had it shipped up to me. Oddly, this was BY FAR the worst packing job I had ever seen, but the unit was barely damaged (the control cover had come off the hinge). I spent some time looking into that unit, and I noticed that I had two units with a number of differences between them, many of which are mentioned in this excellent thread.
To make a long story short, I swapped the newly arrived unit's power supply board into my existing unit, and all was back to proper function with the exception of the memory. So, I swapped in the CPU board from the other unit, too, and the memory works like a charm...but I have not FM reception (as mentioned in the earlier link). These are the two different styles of CPU boards, FWIW.
After all this rambling and background: does anyone have any suggestions for troubleshooting these issues? I presume that the FM reception issue is due to the problem described at the bottom of the page at this link. The memory problem is still well beyond my capacity to even begin checking.
Any thoughts?
