Installed for 6 months in my Laney GH50L, replacing the original 2EL34 (TAD, not so good Chinese)
Solid construction (no microphone to fear)
Well rounded in the graves.Je have chosen on the basis of these lamps in my other GH50L Laney. For the price it is not stolen. Repeat this choice? Providing the kind, I have a pair in reserve, just in case ...
A tip for AFiens Belgian seeking to source lamps: http://www.halfin.com/tubes/html/accueil.asp House very seriously.
