Subject: [AH] JP8 power on problem?



is it normal that when i turn on my jupiter 8, whether it is cold or has 
been on for a while and i'm just resetting it, its volume starts very low 
and gradually ramps up to full volume in about 20 or 30 seconds?

if this is not normal, please advise. i have schematics and soldering iron 
in hand....
thank you all!!

Nah, the normal is having no output at all until the tuning sequence is
complete (some 25 seconds, more or less), and soon as you see "--" on
the display, you are in, and at full volume!

Well, I use an old, stinky, dusty step-down transformer to reduce 220 to
110V, powering both a Memorymoog and a Jupiter 8, with no problema at
all...
