The 1459... well, here's some weirdness for you. The 1459, introduced in the Spring /Summer 1968 catalog, was a small, plain, two-knobbed. dual-input box that pumped out a whopping 3 watts of power. It looked a lot like the 1420, which came along the next year, in F/W 1969. But... there was also a 1459 that was a re-branded 1432, available in 1960.
