Tried nicads and LEDs on both phono and line stage tube cathodes. In the phono stage I use 1.2v infared LEDs and found them better than c size nicads. In the line stage I use 3.6v nicads that function at about 4v with voltage applied. The sound is good. I used to use white 3.6v LEDs in this stage and may go back. The bass may have been better with the LEDs. Other changes in the circuit before I retry though. Because of the low price of components, I suggest you try both and let your ears be the judge.C. -=^v=-
