For Sale: High end Proton stereo equipment.
Includes a rare AA-1150 power amp and AP-100 preamp both working 100% with very little wear. Also included is an AT-300 AM/FM tuner that works and gets good reception but seems to have some issues, may need calibration or repair.
Excellent sound quality with no hum or distortion. All controls tested and working, pots and switches recently cleaned with electronic contact cleaner spray. Amp's large VU meters are both working correctly as are the meter backlights. Preamp has phono inputs that can use either moving magnet or moving coil cartridges, has switch for 100, 200, 320P. All inputs checked and working- phono, tuner, CD, video, and both tape inputs.
The tuner shows some minor cosmetic wear. With a small piece of wire for antenna tunes in stations fine but stereo indicator light does not come on. Scan works but does not stop for any stations. Output level is low- it works on Tuner input but you have to turn up the preamp volume higher than normal. However when plugged into the Phono input the tuner's level sounds fine, sound quality is good, and volume level seems correct. Includes AM loop antenna, antenna mount on back is broken.
