I have tried Deox on the Pitch control and I have tried cycling the pot and the switch, but that has not helped.  As long as I have the front panel "High/Low" switch in the "High" position, the capstan doesn't turn.  I have noticed that I can hear the faint click of a relay from time to time and when that relay clicks the capstan moves very slightly.

Thank you for that tip.  I will try it tomorrow.

Is it possible for the pitch control to affect only the higher speed?

Steve,

Thanks for all the good tips.  I will check the edge connectors and I will blow off the boards.  When I disassembled it to remove the frame, I did disconnect all the boards and I removed them from the chassis.  I had taken off all the exterior panels as well.  It could be that during the re-assembly, something was not seated properly, or got loosened.

Hello Steve,

Thanks for the suggestions.  I will try them and hopefully that will do the trick.  I am traveling right now, so it will have to wait until I return home.

I bought this deck on E-bay, so I don't know about its history prior to my receiving it.  It was damaged in shipping tome and I had to weld the frame, which had broken.  Everything else was fine.  It is a very clean unit, so it appears that it had been cared for.  I have a second deck that a friend gave me for parts.  It was used in my friend's radio station, so it is pretty beat up, but many of the parts are still quite useable.

Thanks again for the tips.

Hello Steve,

Yes, I have the manual and the schematics.  I know about the high/low switch in the back. The problem is that the capstan stops turning when you select the higher speed with the button on the front panel.  It doesn't matter which way the rear switch is set.  I removed and tested the front panel switch and it tests OK.  Whenever I switch it to the higher speed the capstan shuts down.

My Otari 5050BII only runs on the "slow" speeds.  That is if the switch in back is set to low, the switch in front only works at 3 3/4, if the switch in back is set to high, the switch in front only works on 7 1/2.  I have removed and tested the switch for the front panel and it checks out as working properly.  Does anyone have any suggestions as to where I should look next?
