Default Cambridge A60

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?


I don't know that those resistors have to have a lot of power rating. If
you are adjusting quiescent current, you're only talking a few dozen
milliamps. That doesn't drop a lot of voltage and therefore, the power
being dissipated is nominal.
