As yet anther option, you might consider replacing just the second stage 6072 with an ECC99. This will give you a much lower output impedance, even lower than 12AU7, which is a plus, as well as lower gain. However, the ECC99 will pull more current, as with a 12AU7. you would want to reduce the value of the plate resistor to about 22K to 33K, I think. As a final bonus, IMO, the ECC99 sounds better than 12AU7, most of the time.
