Yes, I have a meter. Do I test in the 20k range?
Also - can they be tested in situ - or removed?
When you say 'battery line', is that the line nearest the off switch - positive (earth side) terminal?

I see the 50ohm, but the service sheet has been photocopied with a crease, which inconveniently obliterates the values of R29 & R 30! R 29 looks like it might have a three figure number in ohms - could be 100, but R26 IS in that same line and 2.2k ohms - is that it?

I'll go and take the OC81's off and test. Get back soon.
