Excellent value for money!
This new version of JJ's EL34 is very good, not only in relation to its rather modest price. The tube is very balanced across the whole frequency spectrum, with a general tendency to a slight leanness (which I like). The mids are smooth, and the highs clear, but without sharpness. There is no bottom-end boom or thickening of the lower mids. I use the tube in an audio amplifier, by the way.
