Notes
Low heater current (0.2 A at 6.3 V) makes this tube suitable for series-string heater designs in AC/DC equipment.
Maximum anode dissipation is 6 W — significantly lower than EL84 (12 W). Designed for compact low-power applications.
Maximum screen voltage is 300 V; maximum anode voltage is 300 V.
The valve_equivalents reference lists numerous 'similar' types including EL42, EL82, EL95, 6CL6, 6AG7, and PL82 — however these are not pin-for-pin equivalents and differ in characteristics.
Philips interchange confirms CV3526 military designation and 6BN5 as the American RETMA equivalent.
