I noticed that another member was looking for a part for the loading mechanism. Martin

It's hard to get a resistance test right since the DC resistance will be very low even if working, but I suppose you can compare the two secondary outputs. An AC voltage test would be better. Just lift off the leads to the rectifiers. You can check the rectifiers too then. Martin

Welcome to Beoworld ! If you are sure that it is actually the woofer causing problems, I may be able to help you with a good used replacement woofer but check first that the solder tag rivets are intact. The backside (inside) "rim" of the rivets can sometimes work lose and travel up the flexible lead towards the woofer cone and that can make

OK, that indeed explains the missing startup. I suggest you fix the startup board, disconnect the transformer secondary and power the transformer up normally (through the resistors) while measureing AC on the secondary to see if there is a fault in the transformer. It's a huge transformer, rated at 700W and it's a sturdy build but that doesn't

I agree, it's a wonderful piece. That large surface is so inviting, you almost cannot help placing things on top of it but that would prevent you from using it. It needs to be kept free. Martin

Yes. Though, it may also need to have it's mains fuse(s) changed to suit the new voltage (and current). Halfing the voltage means doubling the current. Martin

The soft-startup sequence is this: - You choose a source on the front panel. - A command to power up the amplifiers are sent from the processor. - Relay RL2 is energized (from the low voltage power supply). This initiates current flow to the large transformer, but through the two power resistors so as not to burn the fuse in your house mains because

No, I'm talking about the +/- 55V secondary voltages. You can also measure if any mains AC arrives at the (large) transformer primary at all. The FM presets are stored in a chip on the processor board. The BM8000 should be able to remember preset stations even if mains was disconnected for a long time (days or more). Make sure you have everything

Sounds like there still is a problem with the startup resistors or their circuit board. RL2 closes, that's fine but RL1 is supposed to close shortly after the "soft" voltage is present on the transformer secondary. If the secondary shows no voltage at all, RL1 will never close and the amplifiers will not get any power. Maybe a burned PCB

The final pieces - yeah right ! Martin
