My brother in law was going to send his stereo tuner off to Good Will today and I happened to stop by and I ended up taking it home. I would like to get some information on it and see if I can use it with my tape recorder and my turntables. It looks like it is more that just a tuner and pre-amp to me and this thing weighs a ton, almost 33lbs.

Here is a picture from e-bay

OK, what model is it?

Probably your typical 70s Pioneer receiver...great find if its in good shape. These were made well and sound great. Don't be scared by the size, some of the higher end models weighed as much as 70 lbs! List the model number here so we can help you with some info.
Some advice: This forum is great for "antique" equipment, but with stuff from the 1970s (aka vintage), http://www.audiokarma.org forums are the place to be. The guys over there are crazy about vintage hi-fi equipment and will be eager to help you get started.

Well now, that sure was a middle of the night senior moment.Been having more and more of those lately.
It is a Pioneer SX 1050

Ed, You've hit the jackpot. This is one of the most highly regarded receivers of the 1970s. Definitely keep it, restore it, and listen to it. You can definitely use it with your tape player and turntable. Just hook both of them up via RCA to the tape monitor and phono inputs on the back. This receiver could probably benefit from a de-oxit treatment and a re-cap.

I think that was 2nd in the product line for 1978 or so (SX-1250 was tops that year). It has a nice toroidal power transformer and lots of features. Definitely a keeper.

Hi! Ed,
That is a really good piece of equipment.

Wish I had one.

Thanks for the feed-back guys, that is just what I'm looking for. It sure has the power with 120 watts out, boy what a surprise. I have it running my turntables and it turns out that the pre-amp is really a pretty good one. It has been decades sense I had listened to my old records and they never sounded so good.

That's 120 watts PER CHANNEL. You might want to snug up the cross bracing on your floor joists.

I have an older Pioneer SX-1010 at 100 watts per channel. It's been in continuous use since the '70s. It still sounds great.

.......And I've got two SX-1250's in the shop for restoration right now - loads of bad/leaky capacitors failing in them.

Gotta love Pioneer stuff - I'm the proud owner of a CT-W505R tape deck. Had it for many years now, it's never gone wrong. Still nowhere near as nice as that tuner amp you have there.

I have a pioneer SX-5 Receiver from 1981, this is a great sounding unit too, seems pioneer where well built.

The SX-1050, like a majority of Pioneer receivers of that era, was an excellent performer. The shortcoming in the design, if you want to call it that, was the main power supply board. I'm referring to the board that has several regulated power supplies on it. Connections work loose and need to be resoldered; and the attrition rate of electrolytic capacitors is (as Repair Tech implied) quite large.

When I see one of those, I treat the switches and controls with Caig DeoxIT D5, and then I do a thoroughgoing restoration of the power supply board. I also burnish (or replace) the protection relay. These are really mandatory services. If I don't do them, the set WILL be returned with an upset customer attached.

When replacing electrolytics in the power supply, use 105-degree devices. If you need lamps, you can get them from Dwojo. Unfortunately, his website is temporarily down due to too many hits this April. So, be patient. The quality of his lamps is unequaled.

Good luck with this!
