[sdiy] Broken CR-78

[Chad Coffman]

Ah, ha! Somebody has noticed me!  :-)

Thanks for the link.

I'm ignorant of these things, but I don't think it's the power supply, 
considering the unit powers up and all. The multimeter is in the mail, so I 
can't test it just yet (I'm merely beginning my crash-course). In the 
meantime, do you suppose it would cause any harm to move that purple ground 
wire back to where it should go--assuming that is where it was originally 
intended to be?

Say the ground wire *was* moved to its present location sometime before the 
unit came into my possession, what possible effect could it have?

I'll have a look at the output audio circuit come daylight --supposing I can 
find it :-)
