12AY7 6072A Electro Harmonix

Similar to the 12AX7 tube, the 12AY7 (also known as a 6072) is a dual triode preamp tube which can plug in the same sockets as a 12AX7 (same pin layout) however it has medium gain compared other 12AX7 range of tubes.

To be clear, they are not a 12AX7, they merely share the same pinout configuration. 

So whats the difference?

The 12AY7 draws a bit more current than a 12AX7 and have a different capacitance between some of the elements in the tube as well as different plate dissipation.  

This tube can often be used as an alternative to a 12AX7 however it will depend on the available current your transformer can provide. Usually, not an issue and most transformers have a bit of spare grunt built in.
