in that case vekked you can use ecler hak fader caps,innofader(you still have innofader right?),pro x fade and most others with a 4mm stem. i like the ecler hak ones..similar to the 707/909 quite tall and thin..innofader is pretty much the same a s the rane(so is the pro x right enough). i actually really like the new fader caps on the 61/62..nicer than the 56/57 ones.
