The 517 makes extensive use of the [[distributed amplifier]] concept. The vertical signal path is | |||
as follows: | |||
* Gain Stage 1: single-ended, six sections, distributed, [[6AK5]] tubes | |||
* Gain Stage 2: single-ended, six sections, distributed, [[6AK5]] tubes | |||
* Gain Stage 3: single-ended, seven sections, distributed, [[6AK5]] tubes | |||
* Signal Delay: 51 feet of RG63U 125-ohm coaxial cable | |||
* Phase Splitter: single-ended in, differential out, three sections, distributed, [[6CB6]] tubes | |||
* Gain Stage 4: differential, six sections, distributed, [[6CB6]] tubes | |||
* Gain Stage 5: differential, twelve sections, distributed, [[6CB6]] tubes | |||
The 517 uses 24kV of acceleration voltage on the CRT. This is generated by the Type 420 High Voltage | |||
Power Supply subsystem in the 517. It uses a 1.8kHz oscillator to produce the high voltage, unlike | |||
other Tek scopes which use HV oscillators in the ultrasonic range. | |||
