It's working. But the capacitor at the power input had both soldered contacts loose - cold joint. It's been repaired, now flawless. Sub Vol and Switch L+R channels are completely independent (not Master Switch). Advantages are Front and Rear output when Fader control (if appropriate connector connection) can regulate the balance of L-R channels.

Funguje. Ale kondenzátor na vstupu napájení měl oba pájené kontakty uvolněné - studený spoj. Bylo opraveno, nyní bez závad. Sub Vol a Volume L+R kanálů je zcela nezávislé (není Master volume). Výhodou je výstup Front a Rear kdy regulací Fader (při vhodném zapojení konektorů) je možné regulovat vyvážení L-R kanálů.
