What qualifies the 5R4 as the "electrical equivalent" to the 596? Would you mind linking me to a source? I ask because they obviously have different filament current draws. I guess "electrical equivalent" does not mean "suitable replacement" in practice? Thanks!
High-rel, high altitude (60000ft) version of 1641, full wave rectifier. 2.3KV PIV, 275mA average current. Designed and manufactured by United Electronics.
Look Up 1641
It has a 3 amp indirect heater versus a 2 amp filament in the 5R4
