This is a construction of cheap home made GainClone based on LM3886. This device is made on a „star” instead of PCBs. There is no complicated selector on relays, but it is mechanical. Second section supports the display. Solution of the problem with the transmission of potentiometer was the same as in old tuners with mechanical scale. This provides the length of signal path is limited to the minimum. The housing was from an old ws 354.
Components:
- BC components capacitors 2200uF
- Elpod resistors
- Rikken in coupling
- signal cable – RK50 (solid copper covered with silver in teflon)
- power supply with Indel toroid 250W 2x24V diodes MUR860
