I have a bit of an issue....
The plastic alignment tools that I bought last year don't seem to work at all on my latest acquisition, the TASCAM 48-OB.
The tools don't fit the 'tape tension' adjustment pots [photos attached]. I tried to make one from a credit card [it fit] but it was impossible to turn [tight fitting]. I need recommendations on what to buy. I don't necessarily wanna go plastic but something which won't pass static or possibly fry the electronics. Any ideas?
