Robert, I have thot about your post for over an hour.  Initially, being a 
newbee, I thot WOW..well removing tubes is quite an extreme adventure!..but 
after running it around..I now feel..what the hell, if all else fails what a 
truely rewarding experience it would be to get with a guru and replace those 
tubes..damn, now that would be fun!!

Thank you so much for your post!!!

Rick
