Tube DIY Asylum

Do It Yourself (DIY) paradise for tube and SET project builders.

I have a preamp (AR LS7) that uses 4 6922's. The front 2 are for the L and R channel gain. The back 2 are for the cathode follower L and R.

How necessary is it to use the same brand tubes for both the gain and CF?

I ask because I have 3 really nice Amperex's so I'm thinking it would be nice to use 2 of them for the gain sections and use and average/test great 'lesser' quality tube for the CF.

I thought the DIY section would be the better place to ask. Appreciate your thoughts.
