Ericsson 6CY5/CATV long-life miniature seven-pin indirectly heated sharp-cutoff RF tetrode for dependable cable-television amplifiers; special long-life variant of 6CY5. Manufacturer base E7-1, cathode/internal shield on pins 2 and 7, grid-1 pin 1, heaters pins 3 and 4, plate pin 5, grid-2 pin 6. Manufacturer publishes cold capacitance measurements with external shield connected to cathode, and typical operation at anode 125 V, but numerical maximum-rating columns in attached OCR are not reliably extractable; no unverified maxima or heater specifications promoted. Operating range/long-life tests and transconductance are manufacturer-specified but source columns not safely attributable.
