SOME REMINDERS REGARDING TUBES
Tubes work with very high supply voltages. There are points inside Creamliner that measure in excess of 350V DC. If touched, those voltages
could be lethal!
Make sure that no pointed objects (especially metal) or liquids penetrate the inside of the unit through its cooling grilles or otherwise. If that
accidentally occurs, immediately pull the plug out of the power socket and wait for the unit to discharge. Creamliner must not be operated if
moisture penetrates inside.
Before opening the unit (to change tube, wipe off moisture, etc) one must disconnect the mains cord and then wait several minutes for the
internal capacitors to discharge.
When mounting in a rack enclosure, always leave an empty space above the Creamliner to ensure proper cooling.
Please do not replace the mains fuse with one of a higher value: use only 600mA@115V (500mA also works fine)
(250 to 300mA@220-240V)

HOW TO CHANGE TUBES
This only applies to a functional unit. Please entrust any repairs to qualified service personnel.
Only an EF-86 (or equivalent, like 6267, 6CF8 or Russian 6J32P) pentode can be used.
Pull out the power cord. Wait for at least 10 minutes for all the capacitors to discharge.
Remove Creamliner’s cover by loosening screws encircled
red
and marked with an
asterisk
(3 on the rear panel and one on the front one) as
well as all side screws (4 on either side). You will need an Allen wrench (some models will have Phillips screws).
While pressing on the edge of the vertical PC board (the one containing the tube) with you right hand, pull out the tube with your left hand.
Small, but fast forward-reverse motion may be needed to loosen the tube from a tight socket. Do not bend the tube much out of the axis
because you can break the pins or cause air to enter the tube and destroy it. Paying attention to the pin alignment, push the replacement tube
into the socket using same motions but in the opposite direction. Make sure it goes in all the way. Due to electric shock danger, testing the
preamp with the lid removed is not recommended. Screw the cover back in place and you’re done.
