[QUOTE="Sarel.wagner, post: 1140092, member: 25509"] Two dead Zeners in the PS this far -33V and -12V, apart from those resistors across the outputs and some items likely on at least one driver board. Most of the PS other voltages are in spec, remarkable really considering that this is a 1968 or most likely a 69 production model. No mains lockout switch, strange but ok. All part numbers are Marantz, and no known substitute references fro Marantz either, this is interesting. Groetnis [/QUOTE]
