We accept all standard methods as well as Venmo, Bank Deposit, Citcon Pay, and more. If you're signed in with Shop Pay, the checkout page will default to this method, but if you wish to use a different option, simply select "Alternative payment methods" from the menu to see all other options.

We accept eligible return or exchange requests within 30 days of receiving your order. Items must be returned in the same condition in which they were sold and in their original packaging. Final Sale, Special Price, and customized items are not eligible for return.

Returns based solely on a change of mind or subjective sound preference are not accepted. If an item arrives damaged, incorrect, or materially different from its description, please contact us so we can review the issue and determine the appropriate resolution.

EU customers can start a return directly through our online return request portal.

If the package was damaged in transit, please also document the condition of the packaging. We’ll review the information and work with you on the appropriate resolution.

For approved claims involving an item that arrived damaged, incorrect, or materially different from its description, return shipping and any standard restocking fee will not apply.

Please contact us at support@soundlumia.com before initiating a return. Every tube is professionally tested before listing and again before shipment, but if you believe there is a performance issue, please send your order number along with a description of the problem and any available test results, photos, or video.

Because readings can vary between testers, equipment, and calibration standards, results from another tester may not exactly match ours. We’ll review the information provided and determine the appropriate next step.

If you need to cancel an order, please contact us at support@soundlumia.com as soon as possible. Orders may be cancelled before processing begins. Once an order has been processed or shipped, cancellation may no longer be possible.

We specialize exclusively in authentic vintage production tubes. Each tube undergoes a careful visual inspection of its internal construction, along with verification of factory and date codes where available. We accurately represent each tube’s manufacturer, production origin, and construction details, giving customers clear information to evaluate its authenticity and provenance.

We use RoeTest V11, a highly sophisticated professional tube tester, to measure important technical parameters for vacuum tubes such as mutual conductance(S), plate current(Ia), input resistance(Ri) etc. The original RoeTest test report for each tube is available for download from the product listing.

“Matched” means the tubes in a pair or set have been individually tested and selected to perform within Soundlumia’s defined matching criteria for that tube type. Matching is based on the electrical measurements most relevant to the tube, which may include transconductance, plate current, or other applicable parameters.

Tubes that meet the required tolerance are grouped into matched pairs or sets and retested before shipment.

Tube test readings can vary between testers due to differences in tester design, calibration, operating conditions, test settings, and measurement method. Even properly functioning testers may not produce identical numerical results for the same tube.

For that reason, readings from different testers should not always be compared as direct equivalents. If you have concerns about a tube you received, send us the tester model, settings, and results so we can review them with you.

Yes. If you’re looking for a specific tube, matched pair, matched set, or something you don’t currently see listed, use our Request a Tube form. Include as much detail as possible about the tube type, brand, quantity, matching needs, and any specific production or construction preferences.
