yes for left/right i have no digtal stuff on mine pre amp. i've build ( still building) the power supply in a differend case. the case of the preamp it self is in a 19" case and is not yet ready i only need to fit a 4 deck attenuator and a source select switch and the left pcb and the connectors at the back of the housing. alot to do i think first i'am on holliday to rimini italy.

I'm also strting with a aleph p 1.7. The mainboard layout is fisished. (http://www.diyaudio.com/forums/showt...119#post207119).

The controls consist of an ATMEGA163, a 4x20 lcd, a volume and input rotary encoder and an iR-eye. Layout finished, not testen and the firmware is not ready yet.

The input selector and volume control relay boards and power supplies must still be designed.
