VHT D-50 (D-Fifty) in great shape; sounds fantastic. Previous owner had it checked by a tech, who also changed the power tubes from 6L6 to EL34s (and adjusted the bias). The front grill cloth was also changed, to better match most cabinets. Includes original foot switch to change channels. $675. Currently in my office and set up to test drive.
Cut and paste D-50 clips, as compared to expensive Two Rock Sensor (read notes for order):
