MAKE ATTENTION : The E288CC are absolute top sounding special quality tubes.
They are not exactly the same as the E88CC / 6922. They require a little more heater current (0.475A against 0.3A) which the amps power supply has to deliver.
Also they have slightly different amplification and plate impedance, but this is not problem in common E88CC circuits.
Very low microphonic, high defined and transparent midrange, test on average of the highest level.
