Fantastic build. If you don't mind telling, where did you buy those meters?

Thanks!
I bought the meters from here https://www.fairradio.com/catalog.php?mode=viewitem&item=4071

They're an amazing deal @ $16.50
They're very high quality, all metal and glass. They're also new in original packaging and everything. I don't know how / why they're so cheap. In any case, I've got a few extras of them as well since at some point I imagine they're going to run out of stock on them, and then that's it.

I opened them up and installed LED's to light them myself though. They don't come with any lighting installed. It's a bit of work to get that done, but not too hard.
 
New preamp, working fine, but some minor things needs still to be finished.
