    I no longer have any equipment that can use these tubes. All are new and unused. If my prices seem very wrong, please let me know.

    Cetron 5R4WGB "Potato Masher" - 4 available. NOS in giant boxes. This is the ruggedized mil-spec version of the 5R4 rectifier that was built for the B52 bomber. Thick squared-off glass envelope, silicone-filled skirted base, extra internal bracing, flight-qualified to 60,000 feet. Physically larger than a standard 5R4: 5-1/4" overall height (4-5/8" seated height), 2-1/16" widest diameter. Made in USA.

    $30 for one, $25 for each additional
    Free US shipping

    PhilipsECG (formerly Sylvania) 5R4GYB     - 5 available. Just a high-quality NOS 5R4. Made in USA.

    PhilipsECG (formerly Sylvania) JAN 6L6WGB - 5 available. All are NOS, but only one has a box. Mil-spec, built in the mid 1980s to better-than-6L6GC specs (so they can be used up to a plate voltage of like 470V). Very well regarded for use in guitar amps as well as hi-fi amps. Made in USA.

    $100 each
    Free US shipping
