My Phi Beta preamp has the switchable option of using 6922 or 8416. I briefly listened to one of my favorite 6922 tubes, Hamburg Valvo Red Labels from the early '60s. I like this tube's combination of body, clarity, and extension. Frankly, it sounded virtually identical to the 8416, so I stuck with the 8416. I guess it's not all that surprising since they're both essentially of the Amperex PQ family.
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.
