Hello all,
I recently inherited an older, high end stereo system from my best friend's dad.

I thought that I could put it together, but I'm a bit confused. Here is what I have:

California Audio Labs Sigma II - Tube Analog Processor (don't even know what that is)
2 Adcom GFA 565 amplifiers
NAD C-160 stereo Pre-amplifier
Dynalab FT101A Analog stereo Tuner
tons of wires with typical RCA phono plugs
some very heavy duty stereo wire that has been soldered together at one end
2 woofers
2 midrange/tweeters

I'm pretty good at connecting devices that have left/right connectors. The most confusing thing is that the amplifiers each have single inputs (not left and right) labelled "unbalanced".

Can anyone give me some advice?

Thanks,
Lynn

Hi Lynn,

I'm no expert (and I'm sure others more knowledgeable will chime in) but my understanding is that devices with weak-signals (e.g. turntables and tuners) plug into a pre-amplifier (in order to boost their signals) and the output from the pre-amp then goes to the amplifier. Output from the amp goes to the speakers. Given that you have a stereo pre-amp there should be 2 output channels and you should connect one output channel to one of the amplifiers and the other output channel to the 2nd amplifier. Does this help at all?

Good luck.

That makes sense.
Why didn't I think of that?

Thanks Wiley, Daryl, and Neverfoundthetime,

Just now, after several trips to buy connectors, I got it all working (yes, started at very low volume and still have it low).
....and OMG - this is a revelation!! I may never leave the house again!

The first CD I'm playing is Eva Cassidy. Wow.

I have seriously not been hearing music as it should be played.

So we are going to have to purchase a good CD player. Any suggestions?

The amps, do indeed get hot. I intend to buy an open shelf table like affair, but should I have a fan or will that just cause interference?

Lynn

Lynn, you need to buy a turntable and borrow a few hundred of Neil's vinyl collection! :-)
