Looks awesome Jason. I've got mine populated, just need to find the time to build it.
Where did you get those tube protectors. I've seen some on eBay but they come from China and I have doubts about the quality and finish of those...
They're China eBay guards. Took a couple weeks to get here. I knew I'd be building one months ago, so I had time to gather everything. The faceplate was etched a couple months ago.
Did you trial it so far into poweramp input (bypassing pre amp) or into pre amp of tube amp and how did the volume output work out?
My amp doesn't have a loop, so I used a 100KA master pot and been running it right into the input/preamp. There's a lot of output available, but it's not drastically more than a lot of other solid state drive boxes I've built.
