Under normal operating conditions, tubes we rebuild or reprocess are guaranteed against defects in materials and workmanship for 3,000 hours, or one year, whichever occurs first. We retain the right to examine defective tubes at our plant without liability for dismantling them, and the option to replace a defective tube or refund money. We accept no other responsibility or liability expressed or implied. Physical damage or damage from improper operating conditions, such as a faulty magnet, which results in burned drift tube or target and loss of vacuum, are not covered under warranty.
Damage resulting from cooling system failure of any description is excluded from warranty coverage.
The internal cavity type is guaranteed against defect in workmanship and materials for 20,000 hours or three years whichever occurs first. The external cavity type is guaranteed against defect in workmanship and materials for 10,000 hours or three years whichever occurs first. We will purchase your used klystron type tubes which are suitable for rebuilding. However the tube must still be under vacuum and in good physical condition. Drift tubes must not be melted and none of the ceramic broken.
