Marantz 2230 (Example — edit or delete me)
A clean 1976 Marantz 2230 — the 30-watt sweet spot, warm tone, that gorgeous blue dial. This is an EXAMPLE entry to show you the fields. Edit it, or delete it and add your own piece.
Full recap of the power supply and tone board. Deoxidized every switch and pot. Replaced dial lamps with warm-white LEDs. Swept FM alignment on the bench. Output measured within spec across the band.
