Very nice and minimal wiring too. Lovely.
Where did you get those ceramic octal sockets ? I have only seen the usual pcb mount ones and ones with tags that are made of skimpy metal. These look like the contact is much more reliable AND easier to clean. I should try and get some.
Edit: I just found that Tube Depot has them. They call them Vintage style ceramic octal sockets !

Thanks Ashok.
here :
2pcs 8Pin Octal Ceramic Chassis Mount Tube Socket EL34 Valve base for Guitar | eBay
between the socket and chassis i have already put rubber ring...around the screw... so the socket dosnt touch the the chassis with all surface.

Hi Nick, yes i will drilling the front panel for extension rods for volume and select.
But now I'm dealing with minimizing mechanical noise from the transformer who has a different behavior now that I put it differently.

The problem with mechanical noise from the transformer solved.
the only problem that remain is big temp inside the box, on aluminium surface i can measure 44-48 Celsius degrees , temp air about 30 Celsius degrees.

The only way to decrease the temp inside the box is drilling the aluminium surface and or the wooden box.
Τhanks Felipe.
I thinking something like this, but how? the aluminium surface is 3mm thick.

Tubes, heater PSUs, HV shunts, all heating up the lone aluminum top plate. Drill circumferential holes around the tubes first. Have holes at the bottom panel (can altogether avoid a bottom panel by only using feet at the wooden plinth's corners if the audio room is never dusted by an unsuspecting person or visited by unwatched kids that may lift the frame and put their hands under it for fun).
If it will still not feel comfortable touching the top, also a large enough sink can lie at the back left unoccupied top panel's area. Same general shape to complement the front one visually. Or try that first to see what happens in case you prefer to avoid holes if possible.

Salas I guessed Niko isn't using bottom plate. I will drill with 5 or 6mm bit surrounding the tubes and near the heat sink areas and will measure again the inside temperature.
