I've just re-capped my 3020 series 20 (I believe it is). The amp now sounds balanced and clear through my workshop test speakers. I've fitted the 1k resistors across R653/4 (470 ohm on mine) according to the instructions for the bias adjustment, but I get readings of around 300mv across these. I didn't expect it to be this high, any advice on this before I proceed?

I made an error in my original post and have rectified it.
R653/4 (yellow-violet-brown) on my board are the ones on the inside of the black thermal trips. I understand that re-capping wont alter DC conditions, but the bias needs checking/adjusting as a matter of course.
