Thanks for your response...
They hooked up to power, no powerlink plugged in...and put the voltmeter on...and adjusted them with no load and cold...
After they adjusted them...are the same...will only play for 3-5 seconds...
I will say..that when they were adjusting the 30mV's....that the green light was staying on..and would go off as it would get out of adjustment....
Ideas??,....
