Horizontal-Deflection Circuits
For Large-Screen Color TV
Features:
• Ability to handle high beam current; average 1.6 mA dc
• Ability to supply as much as 5 mJ of stored energy to the deflection
yoke, which is sufficient for 29-mm-neck and 36.5-mm-neck picture
tubes operated at 29 kV Inominal value)
• Highly reliable circuit which can also be used as a low-voltage power

·Protection against transients above these values induced by arcing or other causes must be provided.
--rhese values do not apply if there is a positive gate signal. Gate must be open or negatively biased.
-Any product of gate current and gate voltage which results in a gate power less than the maximum is permitted, provided that the maximum
reverse gate bias (as specified) is not exceeded.
