Marantz 2225 Sch Free Pdf Manual |best|
A simplified roadmap of the receiver. It shows the signal path: AM/FM tuner → selector switch → tone board → power amp → speaker relays. This is useful for quickly narrowing down which board is faulty (e.g., “I have sound in Aux but not Phono” – you know the issue is on the phono preamp board).
If your FM stereo sounds fuzzy or you cannot lock onto stations, you need the alignment section. This tells you how to adjust the IF (intermediate frequency) transformers and the MPX (multiplex) decoder using a signal generator and oscilloscope. Do not attempt alignment without proper tools—you can permanently detune the receiver. MARANTZ 2225 SCH free pdf manual
