Hey-Hey!!!,
Been looking at the sheet to the EF184/6EJ7. Nice, mu ov 60 and gm of 15 mA/V in triode connection. That leaves a plate z of 4k, which is acceptable.Do you know of a sheet with its triode curves? With that I could generate the cascode plate curves and see what gain I could realize. mu-squared is unbelievable ( 3600 ). If I could get 10% of that I'd be in business.
regards,
Douglas
