Harman Kardon HK825
Stereo Pre-Amplifier (1983-86)
Description
The HK825 preamplifier is designed with attention to even the finest details.
For example, the phono section has Dual RIAA Equalization circuitry. This provides consistently low levels of negative feedback throughout the audio band, and results in improved transient response.
We use low noise FET's in the inputs of both our low and high level stages, for exceptional signal to noise ratio.
The discrete Moving Coil head amplifier allows the use of nearly all MC cartridges, without the need for an expensive add on component. There is also capacitance trim, which obtains the widest, flattest frequency response from your Moving Magnet (MM) cartridge.
In addition, the HK825 is equipped with low negative feedback, and an ultra wideband width of 0.1Hz to 180kHz, which means an incredibly fast transient response, and extremely pure, transparent sound.
To keep interference to a minimum, we take special care with the layout of the circuitry, shielding and wiring. We also utilize only the highest quality, close tolerance components.
Switchable bass and treble turnover frequencies allow for custom tailoring of the tone control characteristics to the listening environment. Tone defeat is available to maximize the purity of the signal when tone controls are not necessary.
Facilities for two tape decks with two way tape copy ability allow for listening to another source while copying from one deck to the other. Loudness, subsonic and high cut filters are also featured.
By the way, since our equipment has always been designed to play original master tapes, we've been ready for digital audio and coming software advances, long before they've been ready for us.

Chasrock Services is proud to be:
( ISTA 6-FEDEX_A Protocol Certified )
This is a registered certification in electronic packaging.
We are approved to safely ship any electronics up to and including 150 lb. packages.
The ISTA 6-FEDEX A Protocol is an
earned certification
.
This is achieved by packaging and shipping electronics to the FedEx packaging laboratory, in Collierville, Tennessee
They put that package through rigorous testing including the following:
Shock Test: (10 random drops from 30 Inches)
Compression Test: The package is then tested in a press at 976.94 lbs. of pressure.
Vibration Test: The package is then put on a vibration table and violently shaken for 45 minutes.
You must pass all three tests without any damage, cosmetically or functionality.
This will be double boxed, surrounded in foam to insure safe undamaged delivery to your home or business. Yes, the shipping cost is a little high, but electronics are fragile and do require a lot of packaging and time to get them done right. I think it's worth a few extra bucks, because they can't be replaced. A
note for you eBay global customers: (
I will get it to your door safely and insured.)
P.S. My posted shipping price is always the total!
I
pride myself on extreme over protective packaging.
(Please see my feedback!)
I will only ship to the 48 contiguous states and I encourage eBay global shipping. Payment is expected in 48 hours of purchase and on the same token they will ship on the next business day. If you need more time, just send a message and we will work something out.
