"Dave Plowman (News)"

I've been fixing a Cambridge A60 - turned out to be nothing more than both
speaker fuses blown. But thought I might as well check the quiescent
current while I'm at it. And the method given in the manual is weird -
replace the PS DC fuses with 15 ohm resistors and measure the voltage
across them.

Not having any high watt 15 ohm resistors to hand is there a different
way?


** Measure the DC voltage across the emitter resistors - easy done with
any DMM.

Then use Ohm's law.
