Some tubes like a lower bias. Some tubes like a hotter bias. You owe it to yourself to experiment lowering and raising the bias from nominal by 10-20ma to see if it gets you the sound you like vs flushing money down the toilet. Those Psvane Sophia whatever princess and the pauper are nothing but TJ tunes relabeled with a funny name. All hail the mighty WE and the so called reissues. But you can buy a few amplifiers for the price of 2 tubes.
2019 300B tubes that are worth the money?
OK, I'm not a super rich audiophile that has unlimited money to blow. I have a pair of Cary 300 CAD300-SE monoblocks i bought used that currently have a pair of TJ/Full music tubes in them. I am, overall, very happy with the sound. So does anyone have a strong opinion that any of the $1000 a pair current production 300b tubes are really worth the money over my $300 pair? Would my money be better spend on a needle upgrade for my turntable? :-)
