Anyone have experience comparing NOS GE vs RCA 6L6?
used as driver tubes on Wavac Ec300b in front of EAT and Takatsuki 300b. The KT66 works best with EAT, the Sylvania Winged-C best with the latter
Its surprising to hear your collective comments on some of the Tung Sol re-issues and the Genelax.  Makes me wonder if the NOS craze is all hype.
truth depends on your vendor, your gear and your ear..i have a mix of new and nos. My 6L6 in a very heavily modified MC240 are Sylvania….but like @noromance i have an open mind….and ear….

I get tubes from only a few places, very reputable..Andy at Vintage tubes and RAM.

best to you on your musical journey
