Installing proper RCA connectors and a "tube-up"
A pair of IKEA wall mounts fits the 4-connectors RCA panels.
The amp line is redone to have the remote controllable pot first and the cathode follower later. To cope with the 50k pot there is 68k resistor in series, this will also make volume pots more centered. In addition a "shelf filter" that compensates for capacitive loading in the pot is added.
