I'm glad you liked it ...
Wow, a gift from Stanley to me, thanks for this! :)Quote:

The construction of made was:
1) I think to put the toroidal away from pcb circuits. For this reason, removed the board with the rca from the back of the box.
I put the toroidal to the left back of case with the circuit at the middle and the right back of case, I fit the usb pcb and the new small pcb with optical receiver.

2) The two main boards were placed together, one above the other, with appropriate spacers. For the circuits joints, were made properly connectors. Also, the potentiometer was removed and lengthened. The big one Panasonic TSUP 15000uF capacitor has removed (it was from an other project with battery).

3) Now there is a room btw pcb and the back of case that is a enough for the 2 Obbligato Premium 15uF/250V (bypassed them with Vishay MKP1837). Also I put the low and high filter according to datasheet Wolfson Dac Chip.
The black cables are RG59 (75 Ohm) and the red ones are interconnect with 68pF capacitance per meter.

4)The major problem was with frontal face of case. I designed and drilled alone using a table-drill and simple HSS drill bits and stepper drills. The letter painting has done from a local printing company on my design with a little euros.
