Greetings to everyone, they gave me an Alan 88s and it is reduced in power, the wattmeter indicates about 1 watt, instead of 5-6 watts, I immediately started to check the Q8 2sc1969 and it is good, how can I continue with the repair? Before disassembling Q7, Q6, Q5 I would like to be able to measure the voltages first, but the voltages are not shown on the diagram, someone can send me the service manual. How should I proceed ? thanks in advance to those who want to answer me.
