Tubes for Cal Audio Labs Alpha Processor

I have a Cal Audio Labs Alpha tube analog processor. Was told certain tubes fail quickly in this unit. Any recommendations? Thank you Dan

All the years I used my Alpha I never had at 12AX7 quit and it was powered up 24/7 for years. I tried a bunch of tubes but the one I liked most at the end of the day was the Groove Tubes GT12AX7M reissue. BTW it reacted well to changes in cabling. Good Luck
