CA 2010 Clicks on Startup

Hi guys, new to the AK world and looking for some advice: when cold, my CA 2010 gets power, and then clicks about 20 to 30 times before starting up [I skipped about 30 seconds in the video, I wanted to add a text screen but was only using the youtube editor, which leaves a lot to be desired]. If its warm, it starts up no problem. Obviously it needs some TLC, the question is does anyone know specifically what problem, or just start checking everything with the multimeter once I open it up?

And second, is it imperative to stop using it immediately?

Check the solder connections for ring cracks on TR401,402,403 and 404..These are located on the power supply/protect board...

IIRC TR402. This transistor normally runs hot..Over the years with heating and cooling cycles it tends to unsolder its self and develops ring cracks in the solder connection. When the transistor heats up it will make a better connection and start working correctly.
