The other day I was donated a BG1202 that did not allow to enjoy records to be listened ,.
I noticed that there was something wrong with the signal path, The cartridge is OK, but from the tonearm socket to the 5-pin DINplug the signal is halted or it disappears.
After I replaced the DINplug : nothing changed. I assume that there is something wrong within the tonearm.Question :is it possible the take the socket off the tonearm?
Hi,Before resorting to that...Check the BG1202 service manual and do a continuity check between the end of the phono cable and its destination inside the BG1202. Then check continuity between the cartridge connector on the tonearm to its destination inside the BG1202. I don't own a BG1202 but I believe there is an audio muting switch in the path so you will need to make sure that is not engaged if you expect to measure from the phono cable to the cartridge connector.
Perhaps the muting switch is the problem.

The muting switch shortens the pickup left and right signal wires to ground, the only way to surely check the wires is desoldering and then check
Collecting Vintage B&O is not a hobby, its a lifestyle.
I had already desoldered the coloured wires and did the continuity check once , I will do it again, but I am atraid that it will not give hope that that the connection with the socket is OK. I will look out for the muting switch. The absence of a pre-amplifyer is not the cause of absence of signal ??
(Wait and see, first I have to do some shopping this morning.)
Sometimes things are not always logically explainable: the solderspot for the white wire was shorted: i do not know why . I did not want to drill out the rivets of that brownish plate in order to investigate that faulty connection. Anyway I connected this white wire directly to the (HvD) one from the cartridge socket (V) and then there was Stereo music again.thanks for the assistance.

That "brownish plate" is part of the muting switch
