So i rechecked the Q5 transistor i had previously replaced with nte 129 and it was reading .0005 where it was supposed to read open i made the mistake of not checking it before i put it in so it might have been bad from the manufacturer unless i gave it too much heat putting it in? anyway got it all back together and did the light bulb limiter test and i was surprised when the light bulb did NOT light up! Do i need to test the output before connecting it to speakers next?
