 I'm looking for two Beolab 4 amplifier boards.

Or Beolab 4000 MK2

Only  amplifier PCB.
If anyone has it, please let me know.

Thanks

Hi marexy

I have one, but it’s been retrieved from a speaker with the dreaded foam rot. Can’t imagine it would be of any use, but if you think it might, let me know

Cheers

Nigel

The BL4000mk1 amplifier PCB and mk2 are different.

The mk1 has the traditional old school STK module, where the mk2 has the ICE power PCB. Totally different design.

I've taken a lot of BL7-1,2 and 6 apart, but not to my knowledge are they the same.

The BL4 and BL4000 are identical as PCB, yes, but differ at the bottom connector and 2 capacitors.
