The D3a LCR Phono Preamplifier in the new chassis is now completed with it's power supply.
The power supply chassis is basically the same as the actual preamp, 434mm wide, 434mm deep and 100mm high plus feet.
The new chassis are designed and laid our such that the phono can be stacked directly on the power supply.
In part 3 I showed some of the construction steps and inside photos of the preamp itself. Hear some views of the power supply.
The rectifier tubes are on a separate plate:
In this case I chose 6BE3 TV damper tubes for their lower height.
The plate with the rectifier tubes is placed under the opening .
This allows the user to easily access the rectifier tubes by removing the square lid.
The chassis shown is still a prototype. New metal plates are made in brushed aluminum for a more refined look. Different woods can be chosen for the sides and also a full metal option is available.
On the photos there are simple rubber feet mounted. The feet are easily replaceable and can be exchanged for some pointe feet which I got made in stainless steel.
The existing portrait style chassis with tubes and transformer covers on top will continue to be offered. Drop me an email if you are interested in a D3a phono in this new look. A matching 10Y line stage is in the works too.
