The sonic device I refer to is made by TIF Industries. Any large A/C 
wholesale supply can get it for you. As good as the VOV may sound the 
stock set-up is very adequate assuming the rest of the system is 
functioning properly. On my cars I just set the suction pressure at 34 
degrees and a high side below 150 psi for R-12.
