For sale 2pairs - close to being quad of the above tubes , bought couple years ago from Hotrox but I didn't get to testing/using these for a while , when tested one tube measuring a fair bit higher than other 3 but as 3 month warranty was over I just ordered another tube which was matched to make 2 pairs - this tube has a different printing, bit more gold as opposed to brownish on 3 other tubes .
Tubes were used for over 6 months, I misplaced original boxes so would be send in EH boxes instead.
