Vac Sig MKII tube circuit upgrade

Anyone have the tube circuit board upgrade on their pre's done.
I want to have mine checked over as I bought her used.
Figure while she's there might as well do the upgrade as that will also give me more tube choice.

Anybody have any thoughts on this.

I believe just the MKII as the IIA has that tube swap option installed already.

Must have understood Vac's website.
The earlier II and IIa can be upgraded so a user can swap out
different tube types.

Knghifi,don't suppose you have been experimenting with different tube types by chance,any thoughts on the extra possibilities.

I see Vac's website now has a picture of the switch and the different tube types the sig will take.
Mine will leave tomorrow for the upgrade.
