- Specifications
The 3EH7 (European designation XF183) is a 9-pin miniature frame-grid semi-remote-cutoff pentode for high-gain RF and IF amplifier stages in radio receivers. Featuring a 3.4V heater for 600mA series-filament circuits, its frame-grid construction delivers high mutual conductance (15,000 microsiemens) and low noise for effective AGC performance in receiver front-ends. Available in new old stock (NOS) and tested used conditions.
