Hi Robert,
Used the procedure on Ron's site to align and neutralize my 511 years ago. Remember using a tube with heat shrink on filament pin for neutralization. Guess I'm someone who does not over think things. My radio is original and the procedure did make a nice improvement in reception. Richard
