what is signal tracing the enzo way?
« on: June 04, 2011, 09:06:09 PM »
i noticed in a post someone recommended using the send outlet of the effects loop to run a signal into the input or return  jack of the effects loop of another amp.if the amp was playing right the preamp would be good on the amp in test. if it didn't get proper sound it was recommended to do the enzo signal tracing test....what is this test....thanks...i use a mfj injector/tracer.it works excellant in testing ic's,output chips,and signal tracing the amp itself.i just fixed a alto powered monitor and i had signal on the output chips output ,but it was really low in volume. when i touched the input jack where i input the signal for the signal tracer it was also extremely low in volume. i thought i had a low battery in the tracer. when i unplugged the input jack with the injector leads still hooked up and touched the positive side of the jack the signal was loud as it usually is when testing. something was loading the circuit. i got my ohmeter out and found 4 shorted zenier diodes.i replaced them and bingo got a loud signal all the way to the output chip.the alto is back and running.could you explain enzo's system of testing...thanks...ed

Congratulations on your repair skills. :tu:
