The Tektronix Type 516 is a monolithic 15 MHz dual-trace oscilloscope introduced in 1960. It contains no transistors. The 516 is essentially a dual trace version of the 515. The main difference between the 515 and 516 is the front end. The 515 uses a conventional rotary switch for the input attenuator while the 516 uses turret attenuators. There are also some differences in the vertical amplifier circuitry. The 515 uses a 6AU6 pentode at the front end. The 516 uses a 6DJ8 dual triode at the front end, and in many other places throughout the instrument.
In a 516, the delay line directly drives the vertical deflection plates of the CRT.
The standard CRT is the T55 with P31 phosphor. It has a post-deflection acceleration voltage of +2335 V. The CRT cathode runs at -1675 V. The HV power supply uses three 5642 rectifier tubes:
- V822 for the CRT cathode voltage
- V832 for the CRT control grid voltage
- V842 for the post-deflection voltage
The LV power supply is typical of 1960's Tek scopes. It provides:
- +400 V unregulated
- +300 V regulated, using one triode of a 6080 as the output tube
- +100 V regulated, using one triode of a 6080 as the output tube
- -150 V regulated, using a 6AU5 tube as the output tube
The reference for the LV supply is a 5651 which produces a -87 V reference, which controls the -150 V supply. The -150 V supply is used as the reference for the +100 V and +300 V supplies.
