No sound Marantz MA6100

tojoko · 27th January 2012, 10:28 PM

I use 8 Marantz MA6100 as amps for an active loudspeaker setup, 1 has the problem, the relais seems to work, but no sound, when power off, one relais (near the front)clicks straight away, another (at the rear) clicks about 3 seconds later, can it be a relaisproblem, if so where can i get the Omron P5GA-28 24 volt (when i read it correctly)relais?

Here is the schematic and parts list

Marantz MA6100 schematic

It shows that relay is a G5PA-28.

Its not the relay.

Its probably bad caps in the signal path. The MA500 suffers from low to no output simply because the caps need changing.

Hi

Thanks for the reply, I already changed all the suspected caps, that was not the problem, the output terminal is bad, i use banana plugs and the minus terminal did not connect to the board....now i put in with screw all is well, relay was broken though, I replaced it with an old DEC DH2TU 24 volt relay, just used the backpins, there is no problem fitting these, the holes are already on the board.

The output terminal are a common problem with ALL the newer Marantz products. Glad to hear you got it.
