How does a dirrect couple circuit work?

It's DC (direct current) coupled, so each stage directly influences the other ones.

Is an ohmeter safer to use than voltmeter?

No, an ohmeter is of very little use in amplifier repair.

To me it is SAFER to use the ohm meter. In fact to use a Huntron which plots componentS current versus voltage give more dimensions than an ohm meter.

Dirus do you supply the schematic with Q134. Is it directly coupled (without coupling capacitors) to the output transistors?

You're obviously not a service engineer
