Vacuum Tube Warranty Information

Vacuum tubes are warrantied for 90 days from the date of shipment, against defects, except in cases of abuse, and replaced with like-item only.

A tube returned for warranty replacement must have a return authorization number from Upscale Audio. This RA number must be written on the outside of the box. Please also include a note in the box that has your name and telephone number, and please explain the issues with the tube. If this information is missing it will delay the shipment of your replacement tube.

Returned tubes must be shipped in sufficient packaging to protect them from damage. Tubes shipped in inadequate packaging will have a voided warranty and will be refused at the customer's expense.

Warranty replacements are not sent in advance. Suspected defective tubes must be returned to Upscale Audio at the customer’s expense. Once we have inspected and verified a tube is defective a replacement is shipped free of charge.

If an expedited replacement is needed it must be paid for in advance (ground shipping is free). When the returned tube has been inspected and verified defective a refund will be processed.

Exceptions to our vacuum tube warranty policy are as follows:

Upscale Audio reserves the right to refuse warranty at our discretion based on the equipment being retubed. You will be notified of any change prior to your order being processed unless the exception is specified below.

Vacuum tubes purchased for use in guitar amps or other pro audio and recording equipment have no warranty. No exceptions.

Upscale Audio is not liable for any damage or injury caused by the improper use of its tubes or the use of an incorrect/incompatible tube type. If you are unsure of what tube or tubes your equipment uses, consult the manufacturer before making a purchase. Using an incompatible tube type may cause severe damage to your equipment and will void your tube's warranty.

Vacuum tubes are electronic parts and are not refundable under any circumstances. This is to protect you, our customer. We are known for the quality of our inventory, and that means we don’t send you tubes that have been out of our possession and possibly used improperly.
