” Much clearer and more musical. Pleasant, well-modulated detail. Possibly a little noisy in the mid-range, but still one of my favorites so far.” Read

  1. It’s quite complicated to roll 12bh7, just because the majority of them are quite exceptional. This one is dark gray plates – a superb tube. A nice balance of details and warmth. Works quite well for vocal and rock music. The only thing that separates it from the best tubes is the amount of air – some 12au7 produce much more air and as a result sound more lively. Still highly recommended.
