Marantz 2235b as preamp using pre-out low signal

Hello,

I have a 2235b that I would like to use as a preamp only.

However when I connect the preout jacks to a power amp, I get a very, very low signal. Like 3/4 volume is barely discernible .

I have a couple of other marantz units from the same era (1150d and a 1070), both of which work fine.

Any thoughts on this?

Thanks
 
If you bought the 2235b used - maybe check the wiring at the preout/main in jacks. It's possible the jacks were acting up at some point and someone bypassed them.
 
I have checked all connectors and cables. Whenever I have the preout cables hooked up the headphone output also is low like the volume control.

There must be something in the circuit that detects a signal connected as no jumpers are required for this receiver.
