I'm not all that familiar with 12AT7 types, but one not previously mentioned is the Sylvania Gold Brand 6201. I use a pair of these in my Lector CDP 0.6T and they work very well for that application although I've not made any comparisons between Sylvanias and other types. Worth looking into.
12AT7 tubes
Hi audiogoners,
I need to replace one tube in my VTL phono stage, it marks 12AT7/ECC81. Is it safe to use tubes brands other than JJ tubes VTL recommends, like mullard or telefunken one.It looks like there are different version of 12AT7 in Mullard.Can someone tell the difference for each version.and your recommendations.Thanks for any information.KB
