It seems most of the DIY on here is for speakers. I want to do some speakers too one day, but the woodworking is a large hurdle for me. It's just so messy.
Anyway, I just pulled the trigger on the bottlehead "Quickie" Pre-amp with the constant current upgrade.
Quickie battery powered directly heated tube preamplifier kit
I'm intrigued by its simplistic design and its pure DC battery operation. It looks rather simple to build and seems to be a good first project. Also, you can't complain about the price.
Anybody else build one of these yet? Any comments or reviews? It is supported pretty well on the BH forums.
Wish me luck
