Rel Sub Woofer Strata II

Hi there,

I am new here and hope that you friendly people can help me.

Is anyone in the possession of the electrical diagram of the Sub Woofer REL StratII?

I am having some trouble with replacing the BUZ900 NPN and the BUz905D PNP. Measuring learns that the Buz900 has a +45volts and in my opinion this must be -45volts

It looks like that the Mosfets are changed, the drivers are BF469 NPN and BF 470 PNP. It should be better if I had this diagram.

Thanks in advance.
