Just when i thought the Komets couldn't get any better... ...one of my NOS Tesla (nonJJ) preamp tubes went microphonic lately and I noticed that Mike at KCA NOS Tubes had some NOS Telefunken 12AX7s in stock. It arrived today and I replaced the Tesla with the Telefunken and the Concorde tone just knocked me on my butt!! I played the Concorde through a Germino 4x12 with Heritage G12H30s and the overdrive was to die for. This is the first time I have ever played a NOS Telefunken, and it is just such a sweet tone you never want to stop playing. Then crank it up and the overdrive just makes you smile like an idiot!! I guess I'm going to have to buy a few more of these tubes before they are all gone!! Thank you Mike!!
