Sumo Polaris 310 vintage power amplifier. Taken apart, cleaned, recapped, dialed in to perfection by factory service manual. It pushes respectable 120 watt/ch at 8 ohm and 176 at 4 ohm while staying stable down to 2 ohm. All that at distortion levels 0.05%. Measured.
I also have matching preamp Sumo Athena that I can include for another $200. It’s a rare and desirable pieces of electronic masterpieces. I’d rather not to sell preamp but it would make sense to keep them together. Don’t mind my cat, she just found a comfortable place.
I’m retired electronic engineer on a mission to save great electronics of the past for future generations to enjoy.
