1201-B

The General Radio 1201-B Unit Regulated Power Supply was introduced in Catalog P (1959) and remained available through Catalog R (1963). Separate versions were available for 105-125 V and 210-250 V line voltages.

The 300 V output is regulated within 1%, the filament supply is unregulated. Both power supplies are isolated from ground.

With its five-pin power connector located on the right side-panel, Type 1201-B is compatible with most Unit instruments.

Specifications

• Outputs
• High Voltage: 300 V_DC (±1%) at 70 mA
• Filament Votage: 6.3 V_AC at 4 A (unregulated)
