I've had some bad luck with the SED winged tubes over the last 18 months, and have 2 go in my Marantz 8, One took a resistor with it.
Best current EL34 tubes
I need a matched quad and noticed that the svetlana. Electro-Harmonix, and JJ are all about the same price. Which are the best ones to buy for natural sound accuracy? Thanks for the help in advance.
