TUBES - input!
!
The smaller 9 pin input tubes in this amplifier are dual triodes meaning the tube does
both channels. This is handy because it ensures the signature of the tube is
maintained across both channels with no variations. It also makes rolling tubes easy
because changing just one tube changes the sound of the entire amplifier.
!
The tube used is our favorite Russian NOS military grade 6N1P-EV. (In Russian that
reads 6h1n-EB, which is what is printed on the tube) Alternately you can use 6922's
which are a touch less warm but slightly more dynamic. Using 6DJ8's may or may not
work depending on the brand and condition of the tube. This is because the voltages
used are on the max end of what a 6DJ8 likes to see. There are two grades of this
tube the better tubes have shiny plated pins, while the consumer grade are un-plated
and dull looking.
!
Expect input tubes to last approximately 6000 hours.
