Murphy's Law: 
"All Tube Testers are Wrong but Some are Useful"
The Results on Your Tube Tester will Vary from These Measurements.

Shipping:
  • I Have Combined Shipping that Adjusts the Shipping Weight for Multiple Items in a Shopping Cart. 
Returns:
  • I Do not Have Many Returns.  
  • My Overall Return Rate is 1.11%.
  • At Times, when I Get a Return Request, I Might Just Refund w/o Returning Depending on the Situation.  Makes No Sense to get a Shorted Tube back in the Mail!
  • If You Need to Return, it is Cool.  
  • Sometimes, Tubes will not Make the Journey to Your Address.  
  • The Frequency is very small, approximately 0.25%.  
  • Usually, the shipping box is destroyed or the Tube Shorts during Shipment.
99% of Audio Tube Buyers are Easy to Work with.  We are family.  That 1% is where the Problems Usually Occur.

We Offer 30 Day Returns with a Free Shipping Label.  Returns Accepted if the Items are Returned in the Exact Same Condition.

Test Driving Tubes and Returns.
  • The Same Exact Tubes Must be Returned.  No Switching Tubes.
  • Tubes must Test with the Same Numbers Upon Return. There is normal variance in Test Results so I take this into Consideration.  I Validate Test Instrumentation in my Professional Life.
  • The Flashing Must be in the Same Condition Upon Return.
  • The Plate Surfaces Must be in the Same Condition upon Return.
  • The Lettering on the Tubes Must Also be in the Same Condition upon Return.
Tube Boxes and Pull Tabs
  • The Pull Tabs on the Tube Boxes Must be in the Same Condition upon Return.
  • Try Opening the Rear Pull Tab First.  If the Tube is Not Accessible from the Rear Tab, Go to the Front Tab. 
  • The Supplied Foam or Cotton must be Installed on Each End of the Tube in Each Box.
  • If the Pull Tabs are Torn Upon Return, the Refunded Price will be Adjusted Accordingly.
Tape Might be Used to Hold End Pull Tabs in Place when You Receive Your Package.
  • The Pull Tabs might be Taped so Tubes do not Fall-Out of Boxes During Shipping.
  • Carefully Cut the Tape on the Pull Tabs to Open Box Pull Tabs.
Inexpensive Retractable Box Cutting Knife Works Well for Opening Tube Boxes. 
  • Use the Blunt Side of a Thin Box Cutting Knife to Aid in Opening the Pull Tabs.
  • Hold Tubes in Areas where there is No Silkscreen.  This is an Art.
