From our review, "When driven into distortion it starts off a bit crunchy like a 6L6 but as you push it, the sound blooms into that singing EL34 tone with great sustain and modest compression." From the manufacturer: "The Tungsol EL34-B is a higher impedance EL34 tube design with increased touch responsiveness and a unique clipping characteristic with a hint of the 6L6 sound."

The Tung-Sol name and trademark have been acquired by the New Sensor Corporation. This new production Tungsol tube is manufactured at their Xpo-Pul factory (also known as Reflektor) in Saratov, Russia. New Sensor is an American corporation and since taking ownership of this factory has been steadily improving the quality of current production tubes.

This tube is as advertised!!! Its airy and has the bass of the 6L6. I think it has better sound stage than the Winged C EL34!!



Swapped out the 6L6's in my Tweaker 40 for a pair of these EL34's. Biased them a little on the hot side and all I can say is KILLER! Complements the screaming preamp beautifully. With the preamp cleaned up and the EL34's pushed, they bloom into pure harmonic delight! I LOVE these power tubes!

Wonderful HiFi tube..


Now that winter is in full swing I've replaced my solid state set-up with all tube gear - they help keep the house warm! I'm using the Tung-Sol EL34B in my Audio Electronics Six-Pacs, driven by a ModWright LS100. This is a strikingly tuneful combination. The Tung-Sols are smooth, airy and with a full, robust bass. They are very low noise and hold a stable bias. I was previously using the Mullard EL34 reissue, which are very nice tubes, but these Tung-Sols are just a bit more lively and tuneful.

Least of my favorite


I've been tube-rolling since I got a Fargen amp (Marshall clone) and Tungsol is the least of my favorite current prod EL34's in stock. I find the bottom end too boomy for my liking. Playing a F# power chord with a light grind on the preamp section only enhances the inherent boominess of the Tungsol. I keep coming back to either Shuguang EL34 or x-pul Mullards.

PrimaLuna Prologue One


I replaced the original tubes from my PrimaLuna Prologue One with these about seven weeks ago. I can't say I have noticed a huge difference. I mostly listen to jazz (all eras) and alternative/electronica from the 80s-00s via an unremarkable Sony CD player; it is only some of the jazz where sounds seems a bit better. But, I am new to hi end audio and realize these tubes may only be showing the weakness of my CD player. At any rate, they do sound good but not much better than stock.
