12AX7 Tube Comparison
large product photo

Country of Origin: Germany

Date: 1960's

Comments: These tubes are legendary for both their sound and their longevity. Claims of 10,000 hours are not uncommon. The sound struck me as a bit sterile. Can a tube be too HiFi? Many folks swear by these, but they aren' t my cuppa tea.
