Hi, as a follow up. Ive been using my BG4000 sparingly and keeping an eye on it.

Ive noticed that there seems so be a bit more crackle now. The cart is in perfect nick, so it cant be that.

Also ive noticed that occasionally it can make a slight grinding sound when the arm returns.

Also very occasionally, the beginning of the record can sound all over the place. With volume and sound quite erratic until maybe the second track starts.

Guess this all wont sound too good. Maybe i need a service. Any suggestion?

Cheers

Tom

If you are not sure of it's history then it will almost certainly need a service.

Lots of little things could add up and cause the problems you describe.

Bare in mind while your cartridge looks A1 the suspension could be on it's way out which may give many of these symptoms.

Also have you checked the tone arm weight with scales? Does the tone arm move freely without the stylus being strained? (look for cantilever movement when playing records - (this could also indicate knackered stylus suspension).

There could also be a problem with the flexible wire loom between tonearm assembly and chassis. This could also tie in with variable volume levels and rubbing noise - things are quite tight under the platter.

I highly recommend getting an experienced B&O restorer to give the thing a full service as per the manual and maybe capacitors / big resistors as mentioned above. Do not send to someone who hasn't had experience of these machines - Too many things to go wrong! I recently got a deck where a previous tech tried to prise the plates up 😉

Anyone recommend a good place to get it serviced.

Im based in South london

Thanks

Tom I would consider starting a new thread requesting help if I were you. There must be known trusted people able to competently tackle the 4000 within a reasonable distance!
