I am looking for the schematic diagram for this receiver. The right channel
has less output then the left channel.

Also what is the difference between the 1000a and the 1000ea?

On second thought, look at the back of the 1000a. IIRC, there are some gain
adjustment pots there which can equalize the channels.

I assume that the tubes have been checked, and the coupling caps replaced.
If not, you NEED to replace ALL the gray Japanese coupling caps as these are
invariably bad. The original output tube coupling caps will make the 7591s
fail in short order.

I've restored a few of these and would be happy to assist.

The 1000 uses 25E5 tubes for the output (PL36). The 1000A uses 7591's in
the output. Both sound very good. The 25E5/PL36 tubes are cheap as well.

I had a similar problem with my Sansui 1000A, and searched the archived posts
for this model, via Google groups. This was a couple of years ago, but another
fellow had the same problem as I did, with a weak side. He indicated the
problem was in the preamp stage and while I don't recall exactly, it seemed to
relate to either a capacitor or resistor, but I DO remember he was very
explicit in describing the fix. I followed his instructions and it fixed mine
too!! I was so encouraged, I rebuilt the receiver, replacing the leaky oil
caps with vintage, milspec oilers, swapped in new power caps, and installed
Russian 7591s. I use it all the time in my garage/shop! I'm sorry I can't
remember the exact fix for the exact problem you described, but I'm sure you
can get the info as I did, with a search for Sansui 1000A repairs through
Google Groups, (searching RAT). Music flows in my house BECAUSE of the
generous contributions from experienced RATs, allowing me to fix my own gear,
where otherwise, I'd be up a creek without a paddle!! Good luck with
your receiver! Robert
Live and let live!

It would be great to know how it's done!

Hi Peter

Did you get hold of a schematic?

I do have one available.
