For an ST-120 type amp, you should have a current capability of about 400 - 425 milliamps.

Are you producing this in europe ? Will it be available for us in europe ?
( asking since it's very expensive and timeconsuming to import from US )

buying it from Bob given the situation we are experiencing now is too expensive. so I would have it made here by a special company, the cost still I don't know but I will know soon
