Guarantee & Returns


All of our tubes are 100% guaranteed to arrive as described, test as described and to be void of any sound defects including microphonics and noise. We offer a 30 day return window from the day you receive the item for all vintage tubes and 90 days for New Production tubes.

PLEASE NOTE - While we accept returns for basically any fault, we DO NOT accept returns for buyer's remorse which includes buyers who decide they don't like the subjective tonal signature of a tube. We have had people exploit our generous return policy to tube roll on our dime so we have a strict policy against this behavior.

Any returned tube must test within 10% of the original value. Any larger variation would indicate many hours of use or abuse and voids our warranty.


Email or call us before return your item. We will email you a pre-paid return shipping label and will issue your refund or exchange when the return arrives. 




We combine shipping. Just make sure that you add all of the items to your cart and checkout only once. If you create separate transactions we will not be able to combine your shipment nor will we automatically refund you the difference. 

All orders will ship at ONE flat rate per order, no matter how many items you order.
