triplett tube tester

I found someone to calibrate my tube tester. Company is Vintage Radio, TV, & electronics loc in Torrance, Ca. Roger did excellent work and when I pick up the tester he went over the different functions and all so included a calibration tube. Great guy fair with good prices www.vintageradiotv.com. The man is a tech tube nut that can do anything. Would go back for any tech. tube work without question. :D
