Dear Beoworld for a few weeks now ive been working on my Beogram 8000 and am at a loss myself so I would like to ask for some help.
A lil backstory of the machine (you can skip this if it means nothing haha)
it was part of a Beosystem 8000 Type 5615 (which I purchased as a whole) from an older gentleman who past away.
When I went to look at the system the daughter was actually surprised to find the BG not to be working, now I thought too that it might be a selling trick But she seems to remember the red dot to supposed to be there and how to operate the BG (she herself was old enough for me not to suspect she looked up all this stuff) also she was really surprised to see that i was tightening the suspension for transport and had no Idea that that existed. So in there might lie the source of what broke.
Now for the behavior of the BG itself.
When I got it and plugged it in it displayed a C in the right bottom corner of the display further the patter light and the red led was lit up on the sensing arm and when I played with the switch (0s1?) the one next to 0tr1 the platter light turned on and off
Now because I was stupid I ordered a capacitor kit from Danish Sound Parts (Btw Dillen is that your company?) and after replacing the C’s I got life.
The 800mV fuse popped after I replaced it with slightly higher rated one the platter is turning backwards and so is the drive motor for the tonearm assembly. i suspect that these might be 2 different problems ( if I play with the control buttons I can get it to reverse direction and almost stop) the tonearm assembly is behaving the same as before the C replacement besides I now have a lil light Illuminated in the base.
I went to check the voltages at
1C27 = 21.5V
1C29= 23.1V not -
1C24= 12.9V
2C28= 4.0V
I also went through checking multiple transistors.
TR 19,20,21,27,29,30,31,32,33 all seem to be fine
also cheched alot of resistors and diodes to many to name
I’m now scratching my head as to what could flip the polarity on 1C29.
Would anyone have a clue? is this information something to work with or am I just completely on the wrong track?
Otr1 (TIP32) and 0ic1 also are seemingly doing there job.
