    Hello,    
              I am building my VTA-ST120 kit and wanted to know if the diode yellow sheet mod will work on the VTA-ST120?  How would I wire it up? Thanks,

    Yes - It will work .. Use 1N4007 diodes and check how to do the mod on the STICKY post above about the "yellow sheet mod". Link is below.

    Thanks, Bob, You have been a great help and resource since I bought the kit. Not to mention replacing the bad KT120. The support that comes with your kits is invaluable!
