Stevens & Billington TX102 Passive preamp Built

Hi. A friend of mine was able to source a used pair of S&B TX102 transformers. He wanted a nice passive preamp. I've told him that there was no point in using these transformers if you don't use good quality parts around them. Passive preamp will reveal any weakness from any crappy parts.
This is what I built for him.

I designed a nice enclosure using Front Panel Express service. They are not cheap but you're certain to get a very professional look and feel. The chassis side panels are made of exotic wood, simply sanded and treated with oil.
