I recently replaced my kit built preamp for basically a new Modwright SWL 9.0 SE Line Stage. It came with an upgraded power supply, new tube board, MWI capacitors. It is everything I hoped it would be, right out of the box.
It just keeps on getting better, so I suggest you give it plenty of break in time. Have you talked to the merchant you bought it from to see what they have to say about it? And, if necessary, what their return policy is?
I hope it works out for, a great preamp makes a big difference.

Dan
