Close · 72/100 confidence. Most values readable. Minor gaps filled by inference from similar circuits.

The JMI T60 was a powerful transistion-era Vox amplifier that bridged the gap between the AC30 and AC100 in the early 1960s lineup. Using EL34 power tubes rather than EL84s, it offered a more muscular, punchy character than the smaller Vox models. It was used primarily as a bass and high-powered guitar amplifier for larger venues.
