The General Radio 1203-B Unit Power Supply was introduced in Catalog O (1956) and remained available through Catalog S (1965). It is a general-purpose unit type power supply, an updated version of the 1203-A with improved high-voltage filtering and a case redesign that moved the fuse holders to the front panel.
There are separate versions for 105-125 V / 210-250 V line voltage. The 300 V output is unregulated, as is the filament supply. Both power supplies are isolated from ground.
With its five-pin power connector located on the right side panel, the 1203-B is compatible with most unit instruments.
Specifications
- Outputs
- High Voltage: 300 VDC at 50 mA
- Filament Voltage: 6.3 VAC at 3 A (unregulated)
- Ripple: Less than 80 mVRMS at full load, 120 Hz
