Do not use in Lone Star Special amp

This Sweetwater ad states this tube is NOS and comes in the Lone Star Special amp. They do come in the amp, and the Mesa folks have come up with three different mods to lower the voltage but this tube still burns out. Usually in a month. Sometimes right away. You need a real NOS tube like Bendix 6106 in the Lone Star Special.
