Re: Damaged 606


 

Always get the power supplies working first. Looks like you need to replace some electrolytics.

Thank you, that makes sense.

I measured the outputs from the low voltate power supplies. Some are of
out of spec, especially -30V. But I'm not sure that would explain the
problem.

-30V is -17.1 (should be at least -29.1)
+15V is +14.9 (ok)
+30V is +27.5 (ok)
+120V is +100.8 (should be +108)
+270V is +261.7 (close, at least +262)
