New old stock, genuine West German made Telefunken ECC808 tubes, in the original sealed boxes, just the thing for that DIY piece or ol' Fisher you've been waiting to put really nice new old stock tubes in.

ECC808 is a special low distortion, low noise, high gain audio triode made by Telefunken, it has electrical characteristics similar to ECC83 or 12AX7 but does not pin out like ECC83 so using in an ECC83 circuit is certainly possible but socket wiring would be different. 

Price is per tube.
