Winter Amps is a California-based builder of handcrafted guitar amplifier clones, specializing in faithful recreations of vintage Sunn tube amps. Their flagship offerings include the Winter Sunn Model T Clone and the Winter Coliseum P.A. Clone, each available in both fully handwired and PCB configurations. The amps are assembled in the USA using custom-wound transformers, JJ 6550 power tubes, 12AX7 preamp tubes, powder-coated chassis, and water jet-cut grills.

The company's approach prioritizes period-accurate reproduction: component placement, chassis dimensions, and wiring layouts are copied from original Sunn units, while a handful of modern conveniences are added, including an FX loop between the preamp and power amp sections, separate 2/4/8/16-ohm speaker jacks, an IEC power inlet, an HT fuse, and a breaker in place of the original mains fuse. International mains voltage options are offered for overseas buyers.

Winter Amps builds are aimed at players chasing the thick, low-end-heavy doom and stoner tones associated with classic Sunn heads, and the brand has been used by the drone-metal band Earth among other heavy guitar and bass acts.

Winter Amps has 2 products cataloged on Equipboard, including Guitar Amplifier Heads.
