MATCHED Pair of NIB RCA 2050 tubes for vintage jukeboxes such as Seeburg and others.  One tube is dated from the 39th week of 1948 and the other from the 52nd week of 1950.  They both feature bottom-mounted, rectangular "D" getters.  CLEAN tubes with clear lettering, nice tight bases, and no loose rattles.  Test VERY STRONG on my B&K 707 tester with identical test numbers!  Results:

TUBE 1:   95
TUBE 2:   95

    Minimum GOOD for this type is 40 and anything over 90 is considered NEW / NOS.  






 


     A little bit about me and my valve testing business.....    I started in the tube business as a small hobby in 2012 testing and selling a few small radio tubes.  Now it has turned into a big hobby as I have sold 1000's and 1,000's of tubes to many happy customers.  I personally inspect and fully test each tube and offer a 30-day unconditional 100% guarantee on all my tested tubes.  I am not a store or full-time business, but I take great pride and care in what I do, and your satisfaction is my number one goal.  
     I have two of the best tube testers ever made that I use to fully test tubes.  The Amplitrex AT-1000 Digital tester and the Triplett 3444 (with digital plate current meter) Tube Analyzer are both mutual conductance testers that can test just about any tube ever made between the two of them and can test for shorts/leakage, noise, gas, emissions, and transconductance.  
    I have an extensive back stock of tubes, so if you have a certain brand or type you are looking for, feel free to contact me.  Thank you for choosing Valves-Tubes!
