Artisan 30 preamp tube roles

Hi there,

I am wondering what the roles of each of the preamp tubes in the Blackstar 30 is.

V1 is the EF86 - The 1 gainstage for the first channel?
V2 is an ECC83 - First gainstage for the second channel?
V3 is an ECC83 - Second gainstage for the second channel?
V4 is an ECC83 - Phase inverter?

If anyone knows please pass it on. :) I am experimenting with different tubes now and this would be valuable information.
