My new Tube Problem

now planing to clone one X-10D for my DVD player

Yaqin compare with X10D which one u prefer

hi cuoreboy, I have some tubes that make the same flash at start-up, an mine work good. I've been told it's OK that some tubes do this!

yeah after starting up the sound is ok no distortion ... but weird only 1 tube is flashing:) thanks for ur info

Even, after the mods i'd made in my X-10D, i still prefer the Yaqin.

ermm bcoz i have the full diagram and circuit board design of X10D but need to do the PCB myself

Ian may have already answered this in another thread...but I would like to know the (manufactured) differences between the Yaquin and Grant Fidelity tube processors. My GF's are breaking in nicely and have added the little something that I was looking for to connect me to the music.
