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 - all charges are combined automatcallly

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