Harman Kardon HK 505
Teknisk funktionel lyd på begge kanaler. Testet på alle indgange. Skifter og knapper fungerer alle. I original tilstand. Der er optisk synlige brugsspor og nogle ridser på frontpanelet. Den drejelige potentiometer til at vælge input har brugsspor, se billeder. Med hensyn til dens alder er den stadig i korrekt teknisk og optisk tilstand.

The Harman Kardon HK 505 is a highly regarded, vintage 60-watt per channel integrated amplifier introduced in 1978, widely celebrated by audiophiles as a hidden gem for its pristine clarity, exceptional bass response, and massive power headroom. Released as the top-of-the-line integrated unit of its series, it famously incorporates the ultra-wideband, low-feedback design philosophies of legendary audio engineer Dr. Matti Otala.
