Ratings & Reviews
Very good performance for a 'stock' power tube
by Noam Bronstein
I recently reviewed the whole fleet of 300B tubes. Shuguang's 300B-98 is a tube you'll find shipping in many Chinese-made amplifiers. But that doesn't mean it should be dismissed. Actually, in many cases I think I'd look at replacing the stock input tubes and lousy caps before I touched these 300B's - they're very good sounding tubes. Musical, detailed, low noise. Only reason for rating it below 4 stars is that it was bettered in some respects by a couple of the others. For my full review see my website, www.wallofsound.ca
300B-98: a bargain
A pleasant and musical 300B at a very reasonable price.
