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`ve heard this linestage many times and it sounds wonderful, but is`nt it hard wired point to point rather than a circuit board?
