Default Question about Vintage Pioneer equipment

My dad is giving me his old Pioneer cs811's and a pioneer sx1050 amp that he just found at a garage sale. I've always been pretty fond of the speakers, but don't know anything about the amp really. He used to have one similar to it, just w/o the tuner, but I was really young and don't remember much about it.

anyone familar with this equipment? comments? opinions?

thanks guys!

SX were receivers. The 1050 was just down from the SX1250 which was rated at 120 W/chan IIRC so that means it was probably rated at 100 W/channel.

Decent as far as the Japanese receivers at the time (late 90s).

that would have been my guess since you knew the other stuff just wanted to clairfy.

I got it all hooked up last night and I'm really happy with it. Everything is really crisp and clear and it will CRANK those sc 811's. I haven't pushed the volume past about 1/4 to 1/3 and they're definatly enough to **** off the neighbors if I'm not carefull.
even with the cabinets low on the floor they stage/image pretty good. I think they'll be great once I build some stands to bring them up to head level. These will definatly be used for my primary music listening set up. i have a cheap-o Technics receiver driving some no-name towers (front and rear) with a pair of Bose cubes for a center channel for my movie watching (until I can get some really nice stuff...who knows when though), but this set up sounds 10x better for music. The instruments sound very live and real.

my only complaint is there is something wrong with the balance knob. The left channel will cut in and out unless I leve something one the bottom right of it to push it up and to the left. There's a broken/breaking connection somewhere in there. Should I pull it apart and see if I can see it/fix it or should I leave this up to the pros? I have some basic soldering skills and can follow a pretty simple circut board. WIll this be big enough/simple enough for me to fix?

oh, here are some pics

You are a very lucky guy. Take good care of that old gear.
You have a good chance that taking off the bottom will expose the PCB with the bad solderings, if any.
It could also be a bad potentiometer who could use a tiny bit of contact cleaner.

Good luck.

how would I go about doing that? Right now it's hooked into the Aux input on the back. I'll also be hooking up an input for my computer and for my DVD player (for CD's and the like)

with out a doubt. My dad used to have a receiver just like this but my aunt overheated it at a party and they got rid of it. He just happened to see this one and grab it for me. This is going to be my new baby

I'll take a look at the internals and see if I can find it. it really soinds like a broke solder because the sound comes back if I push the knob up and to the left or straight in just a tad.

There should be a pre-out/power amp-in set of connections -- plug it into the power-amp ins -- that should give you a good idea of how much the pre-amp section is taking away from the sound. CDs ripped to the iPod in Apple Loseless will probably outperform your CD player.
