12AT7. Used for phase inverters in many amps such as Fender Black and Silver Face, reverb drivers, etc.
12AT7. Used for phase inverters in many amps such as Fender Black and Silver Face, reverb drivers, etc.
This tube is used widely in most of the US-made amps and, in particular, the Fender amps. Fender amps with reverb use two 12AT7s - one for the reverb drive stage, and one used as a phase inverter to drive the push/pull output stage.
The 12AT7s make-up is very similar to the 12AX7 and can be substituted for a 12AX7 in a pinch, although it won't sound very good. Some players do prefer to use the 12AT7 in the driver stage in a Marshall for a cleaner, brighter tone. (The driver or phase inverter is the 12AX7 located nearest the power tubes.)
The 12AT7 is rarely used in a tone-generating stage, but rather in function stages, so this GT-12AT7 is selected for durability. The tube will some times bear the number 6201 as well as 12AT7. This is a special (and more expensive) production run with a rugged construction. The GT-12AT7 is tested under extreme listening conditions and guaranteed to be free of excess noise and microphonic ring.
