Hi, I have a friend that would like to give me a working and in good condition, a HK 570i Receiver for free.  I do not know anything about this receiver from 1982.  I found specs, 45 wpc 8 ohms, high current design at 35 peak amps.  Is it worth taking?  He also wants me to take a matching tape deck which I have no use for.

It is not supposed to have the warm lush sound of the 1970's receivers. It is neutral and dynamic with good clarity from what I have read.  If I take it, I will clean it up and give it to my son of daughter to use in a bedroom system.

Any info will be much appreciated.

Thanks,

Larry

According to this video it's a decent unit:

Last I looked my mother still has the same vintage HK 590i receiver I bought new in ‘83.  I really didn’t know what I was doing at the time but I was never satisfied with the system “carefully curated” from a Navy exchange catalog that paired it with Infinity RS7s.
That said I’d take it back in a heartbeat. My Mom had a mid 70’s HK receiver she bought on the recommendation of her boss at the time who owned a small speaker company.  I remember her system sounded fantastic but that was likely good speaker synergy.  It may have been misplaced but his recommendation planted the perception in my mind of HK of that era being good stuff that persists today.
I doubt this helps much but, if it doesn’t need restoration, I think it’s certainly worth playing with.

Supposedly it was in good working condition when he boxed it.  I am going to take it.  I have to take the tape deck as well.   Not sure what I will do with it.  I got rid of mine 25 years ago.

That looks like a very nice vintage receiver.. My only problem with vintage receivers is they may need some maintenance.. Controls need to be cleaned with Deoxit from time to time or a capacitor might need to be change but generally they sound great.. I would take it.. Below is a fraction of the vintage audio gear that belongs to my buddy Tom.. a true vintage guy.. I really enjoy going over to his place and listening to his gear from days gone by..

Hi,

A great looking vintage system your buddy has!  I bet the JBL's sound fantastic.

Cheers Rod

Hi Rocket,
Those JBL's were a DIY collaboration project if you can believe that and yes, they sound fantastic..

The 570i was the next gen for the 80's. It was advertised as the ultra wide band series of amps, pres, and receivers. They advertised a frequency response up to 100KHz at extremely low distortion.
The audio circuits were all discreet devices and used a new generation of power output transistors. The pre section was pure Class A and the power amp was Class AB as typical of most amps of the era. It was completely DC coupled INPUT to OUTPUT. There are 3 ICs in the tuner section also typical for tuners of the era and was part of a cost reduction and for ease of alignment. The power supply was a single transformer (again a cost reduction from the previous series) but had separate rectifiers and filters for each channel for a quasi dual power supply set up. The main difference from the previous series, IMO, was cost reduction of the chassis, faceplate and switch gear (pots, switches etc.). They didn't look as cool as the older black out dial brushed aluminum units. They are conservatively rated power output wise and measure well below rated distortion (when new). Typical issues with the units (dues to age) are dirty switches and VOL control. easy enough to service unless they blow the output transistors (no longer available and require modification). Otherwise very sturdy units that make great secondary systems or excellent dorm room tunes machines.
