Kenwood GE 7030 Graphic Equalizer (distorted output sound)




This was a tuff one, took me two days to figure this one out. Symptoms: when unit was power on, all functions would work but, The output sound had lost of static in it. After a minute are so It would it clear up and sound good. I anticipate it was probably Cold solder joints. I did find a few, but that didn't fix the problem. All the power reading were good, but I knew it was a problem in the Power section. I figured I better start checking those pesty capacitors. The power section is not that big so I just checked them all. I found numerous Marginal one, the biggie was a 10uf 35volt C93. This baby was reading in the Pico farads. Defiantly "BAD" replaced it and now unit is good as new.Location of capacitor seen below.
