Tek 512 uses a Phantastron oscillator with miller integrator for sweep generation. | Tek 512 uses a [[Phantastron]] oscillator with miller integrator for sweep generation. | ||
The final DC output level of the horizontal amplifier is dropped using a neon divider before driving the deflection plates. | The final DC output level of the horizontal amplifier is dropped using a neon divider before driving the deflection plates. | ||
This is done to achieve better beam focus by approximately matching deflection plate DC level to that of 2nd anode of the CRT. | This is done to achieve better beam focus by approximately matching deflection plate DC level to that of 2nd anode of the CRT. | ||
