EAI TR-48 Analog Computer -8V / 2V Power Supply Schematic
A single-page vector schematic depicting the -8V and 2V power supply circuit of the EAI TR-48 analog computer, drawn by Josh Bensadon on October 10, 2012. The diagram shows a transformer (T1) with 24-ohm secondary windings, rectifier diodes (D1, D2), filter capacitors (C1, C2), fuses (F1 3A, F2 0.5A), a 2N1218 transistor regulator, a zener diode reference (-1.8V, 100mW), and a 22-pin Amphenol connector providing -8V, -8V return, 2V, 2V return, and 2V control outputs; AC input provisions for both 120VAC and 240VAC are shown. A top-view component placement inset is included.
