The STR-445 is a 6L6 that shares some qualities of a 6CA7 in that it has tight, articulate low-end for excellent bass definition along with beautifully balanced mid and a chiming top-end that cuts without harshness. It's a great choice for our Rectifier Series of amps for tightening low-end while adding top end cut in a perfect “Rock/Claw” frequency while avoiding “buzz” and "sizzle" in the upper octave. They're now our standard tube for Dual and Triple Rectifiers and a great “swap and play” update for older Rectos.
