Saw quite a few Z504s at Scalford this year, this is the baby bro. Magical sounding when it's working.
This one received a full electrolytic recap last year and LH channel output transistors but now needs new output transistors on the RH side plus 3 or so resistors (LH side should be fine - see pix on Flikr for snipped blown resistors). Everything easily accessible, circuit diagram supplied. £75 delivered in mainlandUK. Waffle below...
LUXKIT fully applies its ultimate fidelity design concepts in this superb power amp. A simple switching operation affords four amplifier operational modes, including 25 Watts/ch PURE CLASS A, 100 Watts/ch Class AB, 300 Watts Class AB Monaural and 100W Class AB Monaural with PURE CLASS A operational range up to 25 Watts PURE CLASS A operation provides absolutely minimal distortion with no switching, while Class AB operation delivers pure dynamic drive. To cool the amp for stable operation LUXKIT's installed a heat-pipe cooling system for drastically improved thermal transfer. LUXKIT's acclaimed Duo-Beta circuitry assures enhanced sound quality with improved bass range reproduction capability. Other advanced ciruits include cascade bootstrap differential circuit with dual FET and NPN transistors for the first stage, complementary "push-pull" circuit for the pre-driver stage and SEPP (single-ended-push-pull) output for the final stage.
