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.
