This upgrade was exactly what I needed!
have had this preamplifier for about 1.5 years
has replaced the 6922 to some pc88 7V with major upgrade in sound
but 6SN7 tubes I have always had problems, also the original
they have had to be moved regularly around to stop grumbling sound.
The old NOS tubes I have purchased has not been a success!
Some tubes have only made some nasty noises that almost killed my speakers.
no mather what i tried, the sound didnt get there!!
after this brilliant upgrade, the old tubes work!
and the fog has cleared up, it played even ok with the original tubes!
THANKS!
