Description below: Traded for Nightingale Audio cables This amplifier is in excellent condition and works flawlessly, having been checked and verified by a local technician. It delivers an outstanding performance when paired with the right speakers. The XLR balanced inputs are a rare feature for a tube amp at this price point, making it an absolute no-brainer—it’s really that good! I’ve personally tested it with a Schiit Freya preamp in balanced configuration, running a pair of Silverline Speakers, and the results were phenomenal. Perfect for someone ready to elevate their listening experience. Power output:
With KT120 tubes: 80W
With KT88 or 6550 tubes: 60W Local pickup is preferred since the factory carton is missing, but the amp is well-kept and will be safely packed if shipping is required. I’m also including an extra set of tubes and an upgraded fuse with the purchase of this Amp. Whether you’re upgrading your system or diving into the world of tube amps, this is a piece you’ll love. Feel free to reach out with any questions. I am including some tubes I have laying around as a bonus, I cannot verify tube life.
