The Tektronix 125 is a power supply introduced in 1961 for the Type 122 preamplifier. The 125 runs on wall power (mains) and provides three regulated outputs:
- +135 Vdc at 0-20mA, 1mV ripple, tube-based regulation
- -90 Vdc at 0-20mA, 1mV ripple, tube-based regulation
- -6 Vdc at 0.7-4A, 4mV ripple, transistor-based regulation
