Supro 1690T Coronado Amp 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.
