I have the Supratek Sauvignon preamp. I currently am using a Mullard GZ34 as the rectifer tube. Does anyone know if I can substitute a 5Y3GT for the GZ34. Also, is the 5Y3GT the same tube as the 6106? I like the sound of this preamp with RCA 6L6GC's used as the regulators. To me the RCA 6L6GC's sound better than the Genelax KT66's.
