    Description

    super rare Western Electric 300A. The 300A was only made for a very short time about 2 years.
    The 300A is almost never offered for sale anywhere, ever. You may only see 300A for sale on eBay a couple times per year.
    Unfortunately, it test somewhat weak.
    Test on calibrated TV7
    52
    Minimum is 58.
    I also tested on my computerized amplitrex AT1000,it test similar to the TV7 at
    51% emission
    42% transconductance
    300A and 300B are designed to last for many thousands of hours. Even with this one testing what it does it will still last a very, very long time.
    Tube is sold as is, no return.
