Mercury’s Exclusive Tonal Satisfaction Guarantee:

Your complete tonal satisfaction is our only goal. All Mercury Magnetics® APS®, Axiom®, ToneClone®, and Radiospares® products come with a Tonal Satisfaction Guarantee. If you are not satisfied with any Mercury Magnetics® transformer or choke, for any reason, you may return it within 30 days for an exchange or refund (minus all freight). See “Exchange or Refund Policies” below for addendums.

Mercury’s Limited Workmanship Warranty Policy:

Mercury Magnetics® warrants its non-OEM transformers to be free from defects in material and workmanship, if properly installed, under normal use for a period of TEN (10) YEARS from the date of purchase, and by the original owner. Note: this warranty does not cover damage caused by external sources or user error. Defective transformers will be replaced or repaired at our discretion. To the extent permitted by law, the foregoing is exclusive and in lieu of all other warranties or representations whether expressed or implied, including any implied warranty of merchantability or fitness. In no event shall Mercury Magnetics® be liable for special or consequential damages. All warranty returns are examined by our engineering staff to determine the exact cause of failure. This warranty is void if your transformer has been tampered with. See “Exchange or Refund Policies” below for addendums.

Shipping Info:

  • All shipments are F.O.B. Chatsworth, CA

Exchange and Refund Policies:

  • For warranty inquiries on Mercury-made OEM transformers, please contact the manufacturer.
  • Please contact Mercury Magnetics® to discuss making an exchange or to obtain a refund within the thirty (30) day guarantee.
  • Insure your shipment for the invoice amount.
  • Include the original or a copy of the invoice.
  • All transformers must have their identity stickers intact.
  • CODs will not be accepted. Ship prepaid. If the product is found to be defective or in the case of a shipping error, we will issue you a refund for shipping costs.
  • Keep a record of your shipment until you receive your credit or replacement.
  • Returns or exchanges are accepted within a 30 day grace period.
  • Custom Shop orders or Mercury Vintage (restorations and/or rewinds) are covered by the Workmanship Warranty but not our Tonal Guarantee.
  • Wrong parts sent to you due to errors on our part will be replaced or credited at your option. Return freight for that product will also be credited.
  • Do not cut the lead wires until you have tested and listened to the installation. Before cutting the leads, solder and bolt the transformers in, and try them out. When you are satisfied, cut the leads and complete the installation. Cut leads to the transformer will incur a 20% restocking fee. For a refund the product must be returned in salable condition without damage or cut lead wires.
  • Transformers that have been tampered with, modified, or with unauthorized attempted repairs will be rejected. Please package all product carefully.
  • No credit will be issued for less than $5.00US.
  • The use of any type of attenuation device on any Mercury Magnetics transformer will void the 10-Year Warranty. Using “dummy load” or “power attenuators” damages transformers. These type of products wear out power tubes at an accelerated rate, and in some cases may cause RF to be generated in the output, which may destroy the output transformer.
  • Discontinued, obsolete or closeout sale items will not be accepted for return unless they qualify under our warranty.
  • The Mercury Tonal Satisfaction Guarantee and 10-Year Warranty is only extended to transformers and chokes of our upgrade kits. Mercury assumes no responsibility or liability for the amp or the work done to the amplifier.
