Reference DAC PSU

My Reference TDA1541A DAC project comes to the final stage, the housing.

After my decision to make a tube rectifier circuit for the B+ of the Tube-I-zator output stage,

i will make a two case design with a separate case for the PSU.

 

Into the PSU case i will insert the two +/- Power Supply Modules and the Tube rectifier circuit.

The transformer goes on the top of the case in a separate aluminum housing. Also the tube rectifier goes on top.

Because i will use only MKP Mundorf caps in the rectifier circuit, the 47µF and the two 100µF caps goes through the top panel.

 

Because i´ve got a perfect aluminum transformer housing, i´ve made a 1mm deep square to get no visible air gap.
