Harman Kardon 430 *UPGRADED* 90+ PARTS REPLACED - READ DESCRIPTION

For your consideration is a Harman Kardon 430 Twin Powered Stereo Receiver from 1975 in excellent condition with a complete recap and all troublesome transistors replaced (90+ parts replaced and upgraded, details below and pictures of replaced components). Cosmetically I would conservatively rate it 8 out of 10, for sound 10 out of 10 clean pristine sound on all inputs/outputs/functions/switches/buttons. The work done has returned this unit to its full original sonic glory. SEE FULL UPGRADE DETAILS BELOW AND REVIEW ALL PHOTOS CAREFULLY TO EVALUATE CONDITION.

 If you're here, you probably already know but this is a legendary receiver with big, warm clean sound far beyond its rated 25 watts per channel. These units are renowned for their twin amplifier transformers and classic sound. In an era where most companies were chasing more watts, Harman Kardon engineers focused on other metrics to improve sound at lower wattage delivering sound quality that exceeds its power rating and price point, making it a coveted item among collectors and music lovers. 

If you like that Harman Kardon "look", this one has it. I don't think a better looking receiver has been made. This thing looks slick, even in rooms with modern decor. You can't beat the style of this receiver and it has the goods under the hood to match.

COSMETICS - Overall great condition with a few minor notes: There is a dent/ding on the lower right aluminum face where it meets the trim. There are some light scratches on the knobs, aluminum face, side trim pieces. Cover has light scratches but overall great condition as well. Finally there is a small scratch through "man /" on the harman lettering top left. Review all photos for physical condition assessment, I have photographed all imperfections. Zoom photos and you will see this is in overall great cosmetic shape for its age.

UPGRADES - 90+ PARTS REPLACED WITH MODERN EQUIVALENTS FOR IMPROVED PERFORMANCE AND RELIABILITY.

RECAPPED ALL Boards (EVERY SINGLE CAPACITOR IN THIS RECEIVR HAS BEEN REPLACED, 49 total including filter capacitors) as well as all known troublesome/noisy transistors replaced in Power Amp (8 total), Tone Board (6 total), Phono Board (4 total) with modern equivalents for reliable performance and clean, pristine sound across all functions. New variable resistors for dialing in Bias which has been set to factory specifications 25mv. All dial lights, stereo bulb, power button bulb and dial pointer bulb have been replaced with LEDs, a much more reliable option. All pots/switches treated with appropriate deoxit d5 or f5, all functions sound pristine and clear at all levels.

The FM receiver works great and the unit sounds amazing even in my rural part of the country, an attached antenna helps bring in further away stations. It will blow the roof off the house if you want it to, the sound fills the room and stays clean no matter the media or the volume. I strongly recommend playing with "contour" button engaged to hear the full potential of any Harman Kardon from this era, it is an incredibly warm, bright, clean sound. 

This truly is an incredible piece of vintage hifi equipment, these models really do live up to their sterling reputation and this is an opportunity to own a really nice upgraded HK 430. 

I have many years restoring, selling and shipping heavy, vintage stereo equipment. This will be thoroughly and adequately packaged for safe shipping.
