Hi... I am looking at re-tubing my Fender Hot Rod Deluxe. Was reading some reviews of TAD 6L6GC-STR's with a Princton (HRD has very similar power amp). From looking at pictures, they look very similar to JJ's. I know that TAD makes their wide short bottle 6L6WGC, but they are known for being a re-labeler like many other brands. Are the TAD 6L6GC-STR's relabeled/hand picked JJ's?
