Some wiring: bus bar (white wire), control pots, terminals for the heaters connections and some decoupling caps for the 3rd tube plate.
The copper wire for some signal and/or B+ supply.

Very inventive! And very useful for me!
Is seems like you have at your disposal a fantastic crew of designers, mechanics, turners, dryers to achieve such a magnificent result

In fact this is truly a "one man's show..."
I do everything myself and I am fortunate to have a friend's wood working shop, a high level one: there is a good amount of tools and special machines I use to get the needed precision in cutting, driling, painting, etc, to have a decent job done.
Without it I would have not dared to face this kind of work.

Sure!

Actually the tubes are ECC83, KT88 and 5U4G.

I used this chema:
http://www.bonavolta.ch/hobby/en/audio/kt88_1.htm

That toroid feeds ECC83´s and KT88´s filaments. There is a bigger toroid underneath for B+ and 5U4G´s filaments.
Chokes are Hammond 193G and OPT´s Hammond 1627SE.

I will post picture of inside later...

Oh, and it sounds very nice

Here's my just finished line preamp

I have put in all the gadgets I could think of like
- a single contact touch switch to turn it on & off
- remote controlled volume and inputs (dear couch, here I come )
- an EM83 'magic eye' to play to the music - really beautiful to watch. I made it switchable so I can turn it off at will

As most of the fuss in building a preamp is the peripherals, the main circuit is housed on an removable epoxy board so I can try several tubes/circuits in the future
Currently I am using 6H30p in a srpp configuration but I have already started building a board with 76 / 6SN7 (CF)

It drives beautifully my 4-year old 6C33 OTL which I had presented here
