The Tektronix 570 is a curve tracer for tubes.
The 570 contains five transformers:
- T310: center-tapped isolation transformer for plate sweep
- T340: multitap transformer for heater voltages
- T401: multitap autotransformer for selecting peak plate voltage
- T501: transformer for floating supplies and screen voltage supply
- T620: transformer for HV power oscillator for CRT voltages
The screen supply is regulated and uses a 6CD6GA tube as the series regulator.
The vertical and horizontal amplifiers are almost identical. The first stage is a differential amplifier made of two 6AU6 tubes. The second stage is a differential amplifier made of both halves of a 6BQ7A.
