The valves were from Hotrox UK, I was very fussy and bought matched pairs of Electro-Harmonics premium guaranteed valves. It’s 4xEL84s, 2x12ax7s and 1x12au7 from memory. When you bought it, the valves had max 12hrs use - even if that. It was a different amp after fitting the EH valves, it simply became alive. It is singularly, the best Ashdown head ever!! IMO of course 😁
