Subject: [AH] Jupiter-8 Problems


hello all. this is my first post. i have been avidly reading the archives
for
about a year and recently subscribed. so, i would like to extend my thanks
to
all of you for providing such a wealth of knowledge.

now, my problem. i bought a jp-8 awhile ago that was advertised as
being in
excellent condition. it was DOA, and the seller tried to get me to claim
"hidden damages" with UPS. basically, i think he wanted to collect the $2000

he insured it for at my expense. anyway, upon opening it, i noticed that
someone had cracked the power supply circuit board in an attempt to pry it
off. i filled this in with solder and it works. however, when it powers up,
or
when i hit auto-tune, the LEDs stop at "5" and "5"flashes the second time
they
cycle through. i imagine this means that osc. 5 is not tuning properly.
also,
in poly mode, every fifth note is out of tune. so, i guess my question is,
how
do i fix it? i am ordering the service manual from roland.

i feel sorry for this synth (it appears to maybe have been a music
store
rental at one point) and would like to bring it up to snuff. any help would
be
appreciated.

also, are there any AHers that live in the Kent/Akron Ohio area? i
am in
graduate school at kent state.

thank you much-------david

Oh, well...

Chance is that "Osc 5" isn't functioning at all. There IS a problem at that
board anyway. That's why the LED keeps flashing.

Yes you do. There will come a day you might find it the most valuable
document in your studio (apartfrom your new record-deal).
