Subject: Changing tubes in my Fender Super 60

Hi,

If I want to try changing my preamp tubes 12AX7, i have
the following question:

The amp has 2 inputs and 2 preamp tubes 12AX7. Does one
tube belongs to one input? If so, the inputs and the
tubes are parallel?!
It is possible to substitute one 12AX7 for a 12AU7
and one 12AX7 for a 12AY7 without to harm the amp??
If it is possible i could have more flexibility
about using the inputs.

Thank you, and greetings from Austria, Europe

Bernhard.
