Smile Uher uma 1000 bias help please

Hi guys, struggling to bias my Uher uma 1000 power amp,it has no details on the schematic how to do this, the schematic is readily available but cant seem to upload it. It has 2 trim pots, but thats as far as i hve got.
I have replaced a bad transistor and would love to sort this.

Please could someone just take a look at the schematic and tell me where to measure please.
Thanks so much in advance
Richard
