A rare photograph of the old 'Crittall' windows building where 'Brimar' later made valves. #vacuumtube #Brimar #ECC83 #Mullard

Brimar 12AX7 tube

New Old Stock Brimar CV492 valves (still in their original boxes) ready for packing and shipping out to a lucky customer. We ship to most regions on Planet Earth. #brimarvalves #Brimar #Mullard

Brimar 13D8 tube

Tonight I mostly be testing tubes; specifically Brimar 13D8 type tubes. These tubes are a superior replacement for the 12AU7 as they were engineered by Brimar in the early 1960s for precision matched plate currents. #Brimar #thermionicvalves #guitartone

AVO Valve Tester
