Finally the engraved top-, front- & backplate arrived.



Surely you are asking yourself, why i made a 1mm deep square around the place for the transformer...

...now here is the answer



I´ve got a perfect aluminum transformer housing and now it sits perfect without an air gap.


Now it´s time to assemble the parts.

My last thoughts to optimize the Tube-I-zator goes to the B+ High Voltage lines.
To get the maximum flexibility, i have made splitting points in the lines.
The splitting of the anode psu lines brings upgrades possibilities.

You could use e.g. a tube rectifier with C-R-C filter instead of the onboard andoe psu or
switch to a regulated shunt psu, witch in my mind brings the greater sound quality upgrade.

With the experiences from Salas low voltage shunt on my DAC project in mind,
i have made an upgrade module for the Tube-I-zator based on his HV shunt circuit design.

Here it is
