RE this tube

by

I had purchased a pair of these 3 years ago and have no regrets. They sound great in my Cary 300SEI with good highs, mids, and bass. They are tough tubes as well.

Meaty, beaty, big and bouncy!

I recently reviewed the whole fleet of 300B tubes. The JJ is a big, heavy construction tube with a big, full sound - but still lively and fast. Excellent sonics overall. It had the best bass foundation, and was superb on percussion. For my full review see my website, www.wallofsound.ca
