For all tubes priced $10.00 or less we reserve the right to substitute brands if we do not have the entire quantity available for the specific brand you ordered. If we do not have the entire quantity available in stock of a specific tube type you order, we will send the quantity we have available in our inventory and refund you for the difference.

All tubes are tested and guaranteed to function within specified limits for 30 DAYS FROM INVOICE DATE. Be sure to try your new tubes when they arrive. Do not operate power tubes without having you amplifier’s bias checked/adjusted. If you have questions about biasing, see a qualified technician.
Only defective tubes will be considered for return. We do not guarantee any level of performance of tubes in your test equipment nor do we accept returns of tubes you bought for an amp that you later sold. Please do not ask.
Please email a description of the problem, and the amplifier you’re using. We will send you an RMA number. Exchanges only, no cash refunds whatsoever. You are responsible for shipping costs on returning items to us. We cover reshipping costs back to you for qualified returns.

Any package without an RMA number will not be accepted. Defective tubes must be returned within 30 days of purchase, NO exceptions. All tubes, boxes and tube packaging must be returned in original condition. Tubes/boxes not returned in original condition will not be accepted.
