Hey yeah, I noticed that you WERE the only one on
MESSAGES that was concerned about repairing the
performer too. And now I got 2 guys hounding me for a
free schematic. So, we'll just help inform each other
outside the message board I guess. The 470 ohm pots
you need for the EQ section are available from DB
Electronics. in NY. Some one on the Board has his link
and you complained about him... His name is Don and he
is really nice but you have to phone him. So go to his
page and get his Tel#. I bought out all his knobs
(only 7 I still need 3) but he has plenty of 470 ohm
pots left @5.95 ea. Now this is our secrete please; On
EBAY, A sellar; ROAD750 sells 10 100k Piher pots for
2.00 you need these for the volume controls. These are
new old stock but nearly identical to originals: They
have 6 pins so you cut off the 3 you don't need, the
slide is beefier but has no side curb so slides
against, and under the metal top control panal. Keep
this a secret 'cause I don't know what the supply
looks like. His name is Rocky I bought his 10k pot as
well but they are too short and the pins don't line
up. so I pluged 2 100k pots in the EQ section where
they should be 10k (I guess that's OK)but this sectoin
is not working anyway. That's it I have WD Greenhill
electronics in England looking for me as well. I may
buy the Orchestrator on ebay if, for under a 100. to
part out. I know that's sad but what else can we do?
My ebay name is THEHOLLOWEARTH so we'll respect each
others space.
NOW< My Fricking performer#%@* I can't even prove the
100k pots work 'cause all 3 volumes have no effect. I
get sound, but only from signal out. The EQ slides
have no effect, all the lights go on, the modulation
controls work fine. Brass turns on but the controls
have no effect. It sounds great with the sustain and
crescendo working and the vibrato works great too but
that's it. ANY more info you have I can use please
describe the parts. You seem to know more about them
then I do. Please explain which board your talking
about and what a voltage control regulator looks
like..
HELP! ---Todd
