Great replacement tube


I installed this tube in each of a pair of HF-60 amplifier. In this amp, this tube is used as a phase splitter. Sounds beautiful, no difference to my hears with the vintage one. Solid construction and it looks nice with the brown base.

Great sounding tube for Darkvoice 336SE.


Bought the Tung-Sol to replace the factory Shuguang tube on my Darkvoice 336SE. The Tung-Sol completely changed the sound! It sounded so rich and open. This really makes music.

Unfortunately, the dreaded left channel hum came along for the ride. It is not loud, but can be heard without playing music. The right channel is completed silent. This is well documented issue with the 336SE and the solution seems to be to allow the tube to burn-in for at least 72 hours. I am going to let the amp run for 3 days straight.
