Then again, if this were to happen maybe we could then give it cute name like the Lil' Lyr.
This thought has crossed (what's left of) my mind more than once. Adding sockets would be very possible, of that I am sure. There is not much room on that PCB though - it looks pretty crowded already, from the picture on the Schiit website. There may be some room underneath where the glass is currently laying down, but I'd have to get a visual on the underside of the board to be sure. Personally, it would look way better to me with sockets mounted to the top of the chassis, so the whole schebang is on top for easy access.
What I don't know and haven't researched, are what kind of direct substitutes there are for the stock tubes ... and if there are any vintage tubes of this size.
First, I want to mod one of my Bravo V2's to have it handy for comparison. The parts just arrived yesterday. Don't ask me why I keep chasing down that rabbit hole. lol. I'm just stubborn, adventurous, or dumb. Take your pick.
My train of thought also wondered if the Vali could be converted to use a dual triode tube, a la 12AU7's. I have a whole bunch of those laying around But that would be a lot of guesswork on my part. I'm not an EE after all, I'm just brave with a soldering iron hah. But something in me wants to know what a Vali would sound like with a 50's vintage d-getter Mullard driving it.
