As we buy these amazing collections and estates the vacuum tubes tend to be pushed aside.
As our tube inventory expands we have decided to open a dedicated Vacuum tube store.
-Foxy tubes. Buying and selling Vintage NOS and Used Vacuum Tubes.
All vacuum tubes will Ship exclusively with USPS priority mail.
Will be well padded for safe arrival. Please check our feedback on our migsradio eBay store.
We do not set the shipping cost. The eBay calculator is located in the shipping section of the listing and will provide you with the estimated cost.
Shipping from  Ashburnham, MA. 01430  -- Local pick up and testing is always welcome.
We have sold many tubes on migsradio without issue. We will test and provide the gm measurements. 
We deal honestly and enjoy interacting with our buyers. We encourage any comments from our more experienced friends. Please send along any questions or comments. Please remember that eBay tracks our messages back and forth. So be kind...
