Anyone have Teac X1000R repair experience?

tade · 5th September 2011, 10:28 PM

My Teac X1000R reel to reel player has a problem with its right hand capstan/drive system. The capstan breaks a photogate when it falls signalling the motor controller to increase its speed. Unfortunately something is FUBAR and instead of providing smooth control it "jumps" too far up and them drops all the way down signalling the player to stop. I can get it running if i carefully spin the right reel but that is so frustrating...

I wonder if anyone has any experience with these players and maybe knows if it's a blown transistor somewhere. The other reel works great, and it sounds great, so I would love to get this thing working properly.

Can I get it professionally repaired this day and age?

Thanks a lot.

No experience with that particular unit, but I'd look for a dry low ESR cap on the motor control board. Follow motor wiring back to find which board.

oo, ok I can do that.

This would be an old electrolytic? I think it's some sort of simple PLL giving the motor a PWM drive; a bad cap would definitely throw that off.

I REALLY need a scope because there are test points all over :/

I'll dig it out of storage tomorrow. Thanks for the advice.

It's the erratic behavior that leads me to think it might be a cap. A second possibility, and probably a good one, would be high contact resistance on a relay. That also might cause the sort of behaviour you describe. Unlikely a general power supply problem because you describe audio and other drive components as functioning okay. Then after that I'd give a once over to the hub motor itself. A dry bearing might easily show same effect.
Best of luck to you.
