I picked up a kit from Marchand Electronic to build a new crossover. I decided to build the solid state model XM44 with single ended and balanced connections. The tube model was a little over my head although after seeying it in the Marchand shop, It looks mint.
Anyway I was having a few and seemed like a curious question to raise! I quit after a few beers anyway. Over 1400 solder points on the main board on this baby. plus 8 stepped attenuaters, a power supply and a lot of inputs. Its a busy thing that's for sure
