Hello.
I bought a Marantz SR 2000 Receiver from a car boot sale yesterday. Paid £3.
It is very quiet. What I mean, is, in order to listen at a reasonable volume, the control is 2/3 the way round. If I max the control, I only get a more distorted (not louder) sound. It happens on Phono, Line Level and with the tuner section.
I don't think this is by design.
Is it worth my time to find the fault and fix it, or shall I not bother and throw it in the bin? I wonder if anyone has heard of the problem and knows a quick fix?
Any help would be gratfully received.

sorry to say that there nothing special about this amplifier BUT ...
you may always keep as a classic piece and will always sound sweet and coloury ( sound will have a certain colour not real but kinda pleasent )
a pair of small nice speakers and you will have a sweet secondary system
Rule :
to keep it alive for many years to come you need to replace all electrolytics form inside ( all means all and that will include tuner electrolytics also )
spray also pots and switches and you are done for another 30-40 years ...
you may find that after the repair you also have aquiet sensitive tuner
some more info in a can can be found here http://www.diyaudio.com/forums/solid-state/136261-vintage-amplifier-repair-upgrade-manual.html
email me also if you need schematic or aditional help
kind regards sakis
Edit : Do not touch any of the trimers in the tuner ..if you have any trouble in tuner area 99% is coming from electrolytics
as about the fault is 50% electrolytics 50% dirt

Yes, a recap is definitely in order at this point. Might even have something to do with the blown fuse...
