SOME REMINDERS REGARDING TUBES
Tubes work with very high supply voltages. There are points inside
Tantra 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.
Tantra must not be operated if
moisture penetrates inside.
Before opening the unit 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 unit to ensure proper cooling.
Please do not replace the mains fuse with one of a higher value: use only slow-blow types rated 630mA@110-120V or 300-350mA@220-
240V.

either use, modification or servicing this unit.
HOW TO CHANGE TUBES
This only applies to a functional unit. Please entrust any repairs to qualified service personnel.
Only an EF-86 or EF-806/EF-806S (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.
The left tube will influence the tone more than the other one, which will only affect the overdriven signal, when blended in. Both tubes are of
the same type and can be replaced when worn out or if a slightly different tonal texture is desired.
Remove Tantra’s cover by removing all of the screws on the cover.
Pull out the tube while adding a subtle but fast left-right motion 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.
