By the way, my storage 577 has similar "quirks" to yours. I tried adjusting it according to the
manual
and I found the directions very confusing. I finally gave up. Now I am happy that it works well
enough
that I can use it when I need to and if I get a small cloud when I first turn it on pressing the
erase
button always makes it go away so it is not a problem.
Oddly enough storage was/is perfect on my 577. That isn't the problem. A couple of years ago I had a
tant go short. To locate which board was the problem, I unplugged the power supply. Finding the
problem was then obvious and said capacitor was replaced.
Then I plugged one of the darned cluster of harmonica connectors one pin out, and the magic smoke came
out. I was so angry, disappointed with myself, and discouraged I parked it for a year. Then I set
about replacing everything that was clearly ex-silicon and a new clutch of ex-tants. Logic chips had
had some horrid voltage and most were dead. Op-amps were dead. There are two dual JFETS in there, that
were clearly dead - and much to my delight they are still currently available parts.
This saga was behind my word of caution to Wolfgang to check the connectors were plugged in correctly.
Now everything works apart from a remaining gremlin in the step generator or amplifier, so at least
I've put the magic smoke back in at last. It is again parked waiting for another burst of fixit
enthusiasm.
