I have two ADCOM GFA 555 II Amplifiers for sale. I am the original owner, located in the southern California area, and purchased them for $900 each over 20 years ago. I would like to sell them for $350 each, plus shipping and handling, and are still in good condition. I have the manual and both are dual voltage (110/220), because they were purchased in Europe. The price is negotiable based upon a reasonable offer, and would simply like to find a new home for the amplifiers. If interested please contact me via email at exsmoothbmw@yahoo.com.
