What about the values?
Any detail on each component?
You're scheme doesn't show any detail (value) for each component.🙄
Any exotic part used? I can see a large Orange 😎 Drop from the pic.

Neato, just don't forget to oil or varnish that steel otherwise it'll rust up like nuthin'... (at least, it looks like plain steel).

Finished my phono stage !
Here's my latest effort. Just a 12AX7 RCA type phono preamp with passive RIAA. Ok, so there are probably better and neater ways of getting regulated HT, but glow tubes look so cool !
Went for the two box layout to minimise noise and hum. Sounds pretty good to my ears so far.

The one in the middle is but the one closer to the camera looks more like a decatron. SHAME ON YOU! It should be spinning at 60Hz! 😀

The taller tube is indeed an 0A3 but the other is a bit more unusual. It's a G120/1B or CV438 (see http://www.tubecollector.org/cv438.htm). The version I have is a bit taller but it's in a deep socket which was originally for a high voltage rectifier - I'm a bit short of B4 bases. Definitely one of the nicest looking glow tubes I've seen.
If you've just worked out that 0A3 and G120 = 130v and are wondering how the 12AX7's are working at that.. Well, I also have an 0A2 tucked behind the 0A3 giving 280v in total.
