Are you talking about the 12 position Lorlin-UK switch. I have a pair with resistors installed and a pair w/o resistors you are welcome to one pair. I never did like the low number of positions, and the Lorlin switch seemed to me rather fragile. I now only use Khozmo Acoustic 48 positions attenuators, excellent quality and price, you also get to chose better quality resisters but always at a higher cost.
