Hamilton-Kolby SPR-210 Amplifier


The Hamilton-Kolby SPR-210 Amplifier is a premium quality, hand-made mid-size combo amplifier built in the 50's tweed tradition. Powered by a pair of 6L6GC/5881 beam power tubes, this combo amp delivers a classic sound, owing to its finger-jointed pine cabinet, two 10" AlNiCo magnet speakers, and 5F4 vacuum tube circuit. Traditional chassis-mounted steel pots, SwitchcraftTM jacks, eyelet-board construction, and hand-soldered connections make this a rugged, reliable, and road-ready device. An optional reverb module provides a classic "large hall" ambience.
