        I'm not sure about the spot killer circuit, but they're used in
the deflection amps of the 6100 (I've only seen TPS98 transistors there,
too)

        TPS98 crosses to NTE/ECG 194, which I've gotten to work. TIS98
crosses to something else....

        I bought a bunch of TIS98s for .20 a piece, which is a lot better
than $1 - $2 for the NTE parts. I wouldn't imagine that they'd put TIS98
in the manual as a replacement transistor if it didn't work, but then why
did they use TPS98s? <shrug>
