<html> <body> I just want all of you to know how much I appreciate all this talk about Petrof's. Especially you, Les. I have an appt. to tune a 7' version next Tuesday. It hasn't been tuned since last November. After this below freezing weather we're "supposed" to have tonight! With my luck, it'll probably be in the 80's by then. :-D Avery At 02:30 AM 12/8/2005, you wrote: <blockquote type=cite class=cite cite="">Hi Les, I've measured a 17 cent change at A4 in about 12 hours.
