I love these repair and equipment you tube videos as they often indicate short cuts or what is wrong which you can try first. OK I know one should use a sig gen or tracer and go methodically through each stage until you find where the signal vanishes but finding a video with comment such as 'the anode resistor in this model goes low frequently and takes out the valve' can save some time so long as you are careful to check voltages etc about the stage after repair.

Often though I marvel at the number of times some people put their fingers very close to high voltages when pointing to a feature - one wonders how many videos ended early with a quick scream and the item being dropped that we never see.
