The General Radio 1269-A Power Supply was introduced in Catalog R (1963) and remained available through Catalog 1973.

The Type 1269-A is a general-purpose power supply. Although it can be used to supply most unit instruments, its form factor is designed to accommodate oscillator types 1361-A, 1362 and 1363. Having similar dimensions, the 1269-A can be mechanically connected to these oscillators creating a stable combination. Both outputs are regulated and floating from ground.


  • Output Voltage: 300 VDC (±5%) at 50 mA
  • Ripple: Less than 80 mVRMS at full load, 120 Hz
  • Heater Voltage: 6.3 VAC at 3 A
