I may have killed my Pro One...

[Tim Curtis]

Well, now I've really gone and done it...

My Pro One was working just fine, save for some really dirty switches on

the front panel, so I thought I'd give it a cleaning.

I got some DeOxit and opened up the Pro One, removing the PCB from the
front panel.  I cleaned the switches with the DeOxit and also cleaned
the pots as best I could.  Everything felt great.

Then I put it back together and plugged it in - NO OUTPUT!  I opened it
up and checked both the 16 pin cable from the keyboard and the power
cable, as well as checking the connections to the pitch bend and mod
wheel - everything is fine, so I plugged it back in - still nothing.
The gate LED lights every time a key is pressed, so I know that it's
interfacing with the keyboard.  There was no output from either
oscillator or the noise source.  The only audio I DO get is when
powering it down - flip the power switch and it clicks, then gives a
short "DOOoooo...." - definitely a pitch from one of the oscillators.

Any ideas?


Thanks,


Tim
