Re: tone controls not working - there is a switch that turns OFF the tone controls and lets the audio go straight through. In the middle of the tone control knob and lever group.
Please don't use that reporting format again, it causes eyestrain, neck strain, repeated errors in checking, discourages engagement in the discussion, and takes me just too much time to sort out for me or anyone else.

AWR-101 board, these are regulated voltages, unless otherwise indicated. the voltage readings are ground referenced:
pins 2 & 3 +5.4v dc regulated
pins 4 & 5 +13.9v dc regulated
pins 6 & 7 +51.5 v dc regulated this is ok on yours
pins 8, 9 & 10 +36.5v dc regulated seems to be missing
pin 11 +28v dc regulated
pin 13 -13.5v dc regulated this is ok on yours
pin 14 -51.5v dc regulated this is ok on yours
pin 15 -19v dc regulated
pin 17 - 49.5v dc raw unregulated dc to the output transistor circuits,
pin 18 49.5v dc raw unregulated dc to the output transistor circuits
AWM-062 protection board
pin 11 +36.5v dc

pin 8 audio over-current protection input, good would be dc millivolts, bad can go up to over 30v
loosing too much time unraveling and posting this - rebuild your power supply FIRST. At LEAST Q5 is blown, it is undersized for it's tasks, and my recommended replacement for it IS more robust. This is a common failure. The lists are published elsewhere in this forum.
