I've finished mine today : Take a look (click on a photo for full size)

With ground + constant current + 1uF capacitors upgrades - rest all standart parts from mouser.
Right now I'm testing different NOS tubes - best so far : All Valvo, after that ECC83 RCA + ECC82 Valvo then all Sovtek. Whorst : All RFT.
Rectifier : Dario 5Y3GB and MWT 53KU - no sound difference.
I'm absolutely satisfied with that preamp - sounds and looks great !
