The MESA® 6V6 STR 417 is the little brother to the 6L6 and exemplifies classic American tube tone from yesteryear. Extremely sweet and bubbly with a beautifully deep bass and spacious, shimmering highs, this tube defines vintage "Deluxe" styled tones and is a great substitute in Mark & Lone Star Series amplifiers when used with their Tweed Power Switch feature (consult the amplifier owner's manual for proper use).
MESA power tubes are among the highest quality available and selected for their exceptional full-range tonal quality, consistency and reliability. All MESA tubes offer unsurpassed consistency and reliability for ANY tube amplifier, and certainly MESA amplifiers!
Remember… MESA dedication is to create the world’s finest tube amplifiers. And to achieve that goal requires a deeper commitment to tube quality… because the reputation of their amplifiers depends on it.
