Our goal is to ensure your satisfaction with every purchase. Below is our straightforward return policy:
1. Return Window: Tubes may be returned within 30 days of purchase. This provides ample time to evaluate the product and determine if it meets your needs.
2. Condition of Returned Tubes: Returned tubes must be in the same condition as when they were shipped, as determined by our testing standards for mutual conductance, shorts, and leakage. Tubes are thoroughly tested prior to shipping. Returns showing signs of damage due to misuse, defective equipment, or improper handling may not be eligible for a refund or replacement. If a tube is shipped with intact markings, those markings must remain intact for full credit to be issued.
3. Shipping Costs: Shipping charges are non-refundable. For non-defective returns where a replacement is requested, additional shipping fees may apply for the replacement tube.
4. Testing Standards: Tubes are tested for mutual conductance, shorts, and leakage. Please note that tubes are not guaranteed against microphonics or foul odors, as these characteristics can vary depending on the application and storage history.
5. Sweep Tubes: Sweep tubes must be returned within 30 days for evaluation. Returns showing evidence of damage due to misuse, improper application (e.g., use in linear amplifiers), or other forms of mishandling may not qualify for a refund or replacement. After 30 days, sweep tubes are not eligible for return or replacement under any circumstances.
6. Amplifier Tubes: If a tube is determined to have been damaged due to improper equipment settings or operation, it will not be eligible for a refund or replacement. To prevent damage, please ensure that the neutralization of any RF amplifier is adjusted after replacing final tubes, regardless of whether the tubes are matched. Failure to do so may result in tube damage.
Special Note for Audio Amplifier Tubes
Due to the limited availability of new old stock (NOS) audio amplifier tubes, closely matched pairs may be challenging to source. New tubes typically draw more plate current than older tubes, which can lead to excessive current draw if the circuit is not properly biased. This may cause the tube’s plate to glow red, indicating potential damage. To avoid this:
Failure to properly adjust the bias may result in tube damage, and such tubes will not be eligible for replacement. If you are unsure about bias adjustments or tube installation, we recommend consulting a qualified technician.
