The EL37 audio output valve is one of the classic valves and its predecessor was the EL35. At a time of generally low power audio amplification, these valves used in push pull could deliver up to 69 Watts at 2.5% distortion. The EL37 and EL31 are both 25 Watt anode dissipation output valves from the mid 1940s. The main difference is that the ...

2020年11月3日 · WARNING: Tube/Valve amplifiers use potentially LETHAL HIGH VOLTAGES. the safety precautions around high voltages. I just found a pair of Mullard branded EL 37 tubes and wondered if they could be substituted in place of EL34s. I have a Boyuu A9 SE UL amplifier which I built from a kit. Has anyone tried this?

Mullard's flagship 25 Watt anode dissipation audio output pentode was the EL37. In addition to being used on its own as the final stage of an audio power amplifier it was also employed as a driver for high power amplifiers for modulation of small broadcast transmitters.

2012年10月3日 · I just want a direct replacement tube that will perform as well as my EL37's without making any changes, except for a minor bias adjustment. Do you think the 6L6GC is a good way to go? Also if you could recommend a brand & a …

2011年12月24日 · In this regard, an EL37 is much closer to the capabilities of a 6L6GC than an EL34. Indeed, while the EL37 is capable of slightly more power output than a 6L6GC is in this setting, in the real world, the actual performance differences between the two tubes are very small, with both producing significantly less power output than an EL34 will in ...

Being a substitute for the 6L6GC and its variants, The Mullard made EL37 / CV586 is a very rare tube with excellent tone and durability. We have a mix of tubes with black bases, dual getter rings and black plates in the original boxes.
