Corona DS-538MG Digital Servos Burn at Idle
Posted: Thu Aug 29, 2013 11:01 pm
We have read the internet comments about the DS-538MGs burning up while sitting at idle; no input-signal changes, no end-of-travel jams. I must admit I was skeptical...until we experienced this same condition. So far, I've heard of five such failures, two of which occurred in my club. If the pix comes thru, you'll see a hole burned in the bottom cover, with significant melt-back of the plastic. In the hole, are the remains of the two amplifier ICs.
