Close · 77/100 confidence. Most values readable. Minor gaps filled by inference from similar circuits.

The Supro Supreme is the top-of-the-line Supro combo from Valco's 1950s and early 1960s range, offering the most power and features available from the brand at that time. It features multiple inputs, tremolo, reverb, and an extended tone control section unusual for its era. The Supreme represents Valco's most complete statement as an amplifier manufacturer before the British Invasion changed market priorities.
