10EM7 Vacuum Tube – Dissimilar Dual-Triode for TV Vertical Deflection

The 10EM7 packages two dissimilar triode sections in one envelope — the same design family as the 13EM7 — built for the vertical-deflection stage of television receivers.

• Tube type: Dissimilar dual triode
• Heater: ~10V AC (part of the "10" series TV deflection tube family)
• Typical use: Vertical-deflection oscillator/amplifier stage in television receivers

Same internal design as the 13EM7, differing only in heater voltage.
