Slider pots

[Harry Kershaw]

Hi
I have a vintage Tascam Porta 05 mini studio that I am trying to restore. I have repaired all the running gear (belts etc but I am having problems with the slider/faders on the mixer section.
It is a four track machine and there are four channel sliders and a master (five in total). Channel two doesn't seem to work and is on all the time. I take it this must be a faulty pot. The information on the side of the slider is:- 223E 50KA (photos available) it is 60mm long.
I am by no means an electronics expert but am able to solder satisfactorily.
As I cannot get spares from Tascam does anyone know where I could get a suitable replacement pot for this machine. Also would there be any points I had to be careful of whilst carrying out the work.

Thanks in anticipation.

Harry

The 50KA almost certainly means that the maximum resistance is 50kΩ and that it is a logarithmic (or audio) taper.

Everything else about the pot is likely to be related to mounting and track length etc. Just find one that fits.

You could look on rs's web site http://uk.rs-online.con

While you're looking for replacements, you might try the spray-can contact cleaner stuff to see if you can extend the life of the sliders.

Thanks already done that.
