6cylindersovertexas: Thanks, but yes I knew that. I'm concerned about my fittings matching the new rotary compressors. I don't want to have to buy new hoses. Regardless, I may go with a York to Sanden conversion setup if I can't find a cheap York.
Your point about the power loss is well taken. My 3/4 ton needs every horse that the 235 can muster.
