Default Just got me a realistic STA 2080

Well my ss amp made all the speakers sound well smeared and indistinguishable from one another, a tin can fisher and a good wharfedale both sounded about the same.
So realistic 2080 how is it.
Is there any mods for getting it to be better, and is there a standard check I have to do and replace cos its 30 years old.
It has 1 light out on one of the face dials - the signal strength one if I recall. Light only, the meter works.
Cool.
Srinath.

Default Ol' gear...

Nice find snagging your STA.
I sold Realistic gear when it was in its heyday (Seventies).
Radio Shack contracted out with Pioneer and I believe Sansui and Kenwood.
My best guess is yours is a Kenwood based unit. These series of receivers are robust & virtually indestructable.
I would suggest getting the correct lamp for your meter(Maybe hard to find), and quite probably she needs some new Power Supply capacitors, as they are thirty years old now.. Don't be tempted to crank up the values on the capacitors....but you can bump up the VOLTAGE values.... no harm done. Don't be afraid to spend a little extra for "name brand" caps.....just don't over do it.
A technician could dial in your tuner...but you can do the rest.

Oh well, its not working on the right channel.
Both A and B dont have wattage to the right.
I guess I open it now, and see what it looks like.
Cool.

Opened the right side, man is there a ton of stuff in there.
So where is the right channel outputs ? Assuming that is the likely spot of problem.
Cool.

Ok I figured it out (yes operator error - sorta).
That cross bridge between the pre out and right was not there ... I swapped it from the left to the right pins and voila, only right, no left.
So I need a hanger wire bent into that shape ?
Cool.
Srinath.

Just make yourself a short RCA-RCA patch cable. It will likely sound better than the folded steel,

There is a whole lot you can do to soup this puppy up... as Richard suggests you start with elecos. Modern caps are better than vinatge, and those old resistors drift in value.

But before doing any but basic main you need a schema (even if you make it yourself) so you can decide what to do. Also whether you want to "restore" it and maintain collectors value, or you want to make it the best it can be.

I think I need it to be the best it can be, however I opened it and I find it really scary. Solid state stuff, like my 60 inch tv didn't look this bad. This was painfully cluttered inside it.
I have found pics of it on line, but I'll post pics of mine.
Thanks for the ideas.
Cool.
Srinath.

Worked for Radio-Shack part time in the 1970s and early 1980s - The STA-2080 is solid state and probably represents one of the better receivers they oem'd. This should be posted over in the solid state forum..

Gaaa I thought it was tube. Sheesh ... I was looking for tube and feeling all smug I got this one.
Sorry mods, please move it to tube forum.
Cool.
