The Supro brand has brought back one of its most iconic designs from the 60s - the Coronado. Their flagship amplifier back in the day, this powerful combo has been lovingly recreated, with some modern refinements ensuring that it meets the standards of today's players.

The Coronado 1690T Amp!

American Tones

Driven by a pair of 'Class A' 6L6 power tubes, the Coronado provides that unmistakable American sound. With 35W of headroom, this amplifier has a large, vibrant clean tone that is projected beautifully through its pair of 10-inch Supro-designed CR10 speakers.

Here's what Supro say about the 1690T Coronado 2x10 Combo:

The 1690T Coronado is our top-of-the-line 1964 reissue Supro tube amplifier. True to the original, this luxurious 2 x 10, 35-Watt combo delivers remarkable dynamic range with a clear, full sound. The Coronado maintains clean headroom throughout a large chunk of the volume control’s range, making it an excellent platform for a myriad of musical styles, from fat round jazz tones to country twang, stinging blues and— when ramped up to full throttle—raging rock & roll.

The bold and classic American tone of the 1690T amp is defined by the “Class A” dual-6L6, tube-rectified Supro power amp that is also found in the Thunderbolt amp. Feeding all of this touch-sensitive power through a pair of high-power Supro drivers, the Coronado’s tone remains clear, even when it’s distorted. The 1690T has ample headroom to accommodate pedals and gets easily loud enough to play large-venue and theater stages.

The Coronado’s two-channel preamp provides a broad spectrum of sounds with its dual volume and tone controls as well as shared tremolo circuit. Plugging into IN 1+2 links both preamp channels in parallel for double the input signal and double the gain. This clever topology lets you hit the power amp as hard as necessary and even allows “channel switching” in its purest form, using a simple A/B switch.

The 1964 reissue Supro Coronado’s vintage-correct, lightweight cabinet carries a matched pair of custom 10” Supro speakers to deliver serious punch and remarkable articulation even when the amp is pushed into exultant tube saturation. Custom-designed high-power Supro transformers and matched 5881/6L6WGC military-spec power tubes ensure consistent vintage tone night after night.
