I got a nice Kenwood KA-3500 amplifier from a friend wich I'm planning to re-cap. First I measured the DC offset wich is aprox 28mV per channel, so that's not too bad. Next I wanted to measure the bias but the service manual is not clear to me, so I'm hoping some can help me out.

Do I need to attach the propes like this to measure the bias:

Try to use mini grabbers for this job. Reduces the risk of slipping from high to almost none. :)
