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.
Made in U.S.A.
