While checking the output transistors in my 565 (in circuit) I measured 0.018 ohms when checking emitter to base, not .05 .06 volts. All the outputs I checked ,even on the working amp tested this way. Does this mean that they are shorted?. I have not been able to go further until this question is answered. Yes, this is the first transistor amp I've tested. Please help. Thanks, Kevin
Use diode testing mode, not resistance, for measuring pn-junctions. The "resistance" of a pn-junction depends on the test current applied, so you are at the mercy of the test-current your meter happens to use. Diode test mode measures voltage, not resistance, so expect 0.5 to 0.6V for a working forward-biased pn-junction, 0.25V or so for Schottky junction.
Needless to say, unplug the amplifier from AC power before any such testing.
Do not just turn it off.
