Hello Good People, This is Dave. I have four JJ 6L6GC's with a sku #T-6L6GC-JJ-MQ They were given as a gift bought thru amazon, And am happy with them! My question is, on all four tube boxes a label was marked 17/2.5 Could you tell me what this means? The values? Thank you in advance,I would really appreciate it! I will look to "Amplifiedparts" for future tube/electronics needs. Best Regards, Dave
