    GT-6550-R Duet
    Highest power pentode for use in Marshall, Hiwatt, Ampeg SVT, the GT amps and a few other higher powered amps. Also popular for HiFi amps. Newest entry, power and quality should mean long life. Excellent response, yet it's easier to push into distortion than "A" version, a little harder sounding than "C".

    Country of origin: Russia

    A great replacement tube for your guitar amp. Order today!

    Man these tubes make my Jcm 800 2203x sound so massive gives it more headroom plus man the bass is more robust like a heavy thump plu8s it stays clean at high volumes=)
