I purchased my p t r about a year ago and have been trying to find the best use for it every since. What I mean is, I have a lot of audio equipment and several places it would work well. Bottom line is, my plextalk now occupies a place of prominence by my chair in our living room. I have many audio sources coming to my receiver at my chair and need to record something from time to time. My question is just this. I would like to tern off the sleep timer and just leave the machine on all the time. Of course what I am wondering is, will this shorten the life of the p t r or will it even matter in the long run. I have several pieces of gear I leave on all the time and that fact doesn't seam to affect in any way. I even think some times that may be best. All ideas will be taken in to consideration. Phil Parr.
