I'm not aware of an upgrade to the Sig. 2A, his website does not say there is an upgrade as well.
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.
