This is unbalanced version of the Aleph series preamplifiers.

My version is combined from Aleph L 1.2 with Aleph P 1.0 (6 bit) volume control.

More pictures coming soon!!!

Ongoing:

- Design of the chassis

- Design of the control and display module

The whole PCB was designed based on Nelson's original layout (can be found in the service manual). The PCB was made at home.

Components:

- Holco audiophile resistors (1/4 and 1/2W)
- Panasonic 3W resistors
- Matched FET tarnsistors (IRF series)
- Multicap capacitors
- Nippon Chemicon PSU capacitors
- Kimber hook-up wires
- Takamisawa RY series relays with gold plated contacts

All the things here only for DIY. Not for commercial use!
