The TDSL (Tube Data Sheet Locator) Personal Edition provides information right on your PC for a large number of vacuum tubes.

Advanced searching facilities help you to compare different types and make substitutes for hard to find vacuum tubes.

 

The item most overlooked when ordering a custom radio is the microphone.  Your new tuned radio will NOT sound great with a stock mic on it.
 If your CB is more than a tool for work, you NEED to upgrade your microphone.  My personal favorites are the Astatic 636L and RD104E.

 

If you place an order from outside the continental USA, we will calculate your actual shipping and send you a PayPal payment request.
