Tube Placement and Installation Instructions
Please read the last paragraph from the section: TUBE CHOICES FOR
THE KOMET
AMPLIFIER before you install your amplifier’s tubes.
Note:
The power tube bias on your Komet
amplifier is set here at our shop before
the amplifier is packaged and shipped. You can begin to play your amplifier as
soon as you install the three pre amp tubes, the two power tubes, and the rectifier
tube. You can easily check the mV
( millivolt )
bias status with a digital multimeter
meter with an mV setting. Please carefully review the section
"
Biasing The Komet
Amplifier
"
for the biasing procedure and details. The amplifier should read
anywhere from 28mV to 30mV, depending on your AC wall voltage.
Carefully un-screw the six insertion screws from back panel, then remove back
panel
evenly
with both hands.
You are now looking at the back of your amplifier. Observe the tube placement.
There are six tube sockets in total. Starting from the left, the first three tube
sockets, ( V1, V2 and V3 ), are nine pin, miniature pre amp tube types. The last
three sockets, ( V4, V5 ), are 8 pin octal types.
Each tube enclosed is labeled with a number for the tube’s required placement
within the amp.
V1, V2 and V3 are 12AX7 pre amp tubes.
V4 and V5 are matched Winged “ C “ JSC Svetlana EL 34 power tubes.
Please note that each tube‘s pin configuration must be properly and perfectly
aligned with the tube socket for installation. Gently install each tube in the correc-
corresponding tube socket.
NEVER -
force a tube into a socket.
Please have a qualified technician install the tubes if you are not comfortable with
this procedure.
Note:
“ V “
stands for
“
valve “
, - term as used in England for audio tubes.
