The Tung-Sol EF806 SG / 6267 Gold Pin is a special quality – low noise EF86 / 6267. These tubes are beautiful in mic preamps, hi-fi equipment and guitar amps. If you are a Vox owner, then you have to try these in your amp. They have smooth tone, but are very articulate. With their solid shield, these EF806 remind us of the old Telefunken EF86 from the 50’s.
