These guys fixed a Levinson ML7a preamp and a Pioneer TX-9100 tuner for me. The Pioneer was a challenge. The power switch was bad. As the switch itself is no longer available from Pioneer, they took it apart and replaced its guts. I also had them realign the tuner and replace burned out light bulbs. The tuner now sounds, works and looks like it did in 1973. I am very pleased with their service.
