Known Equivalents & Substitutes

6HV5

Similar Tubes (Not Drop-In Compatible)

6HS5

Same Compactron beam triode family and identical pinout (12GY). Lower heater current (1.5A vs 1.8A) and lower Pa_max (30W vs 35W)

6JD5

Similar Compactron beam triode for horizontal deflection, but higher heater current (2.5A) and better linearity characteristics

6JK5

Same Compactron beam triode family for horizontal deflection — radiomuseum lists as equivalent to 6HS5/6HV5 group

Notes

Sharp cutoff beam triode for horizontal deflection and high-voltage regulation. Compactron 12-pin base (Duodecar B12C).
Pins 5, 6, 8, 9 are internal connections — do not connect externally.
TDSL lists 6HV5 as a substitute with 'different rating or performance'. The 6HV5A is the improved version.
Application data is for pulse regulator service: Va=3500V, Vg1=-4.4V, Ia=300mA peak, ra=4600 ohm, gm=65 mA/V.
