Hi, Paul, Thanks for the tip. The cool thing (ha) about my cold playback technique was I tested it with Sony PR-150--one of the poster children for squealing--and it worked fine cold. I opened the fridge door and the squealing restarted. I closed the door and I could hear it stop in less than a minute. So, yes, the PR99 is not ideal for this. If I get to play the tape, I would use the A80, except that it's 3.75 in/s and I haven't done the 3.75 mod yet to any of my machines. I could use an A810, but I might use the Racal Store 4DS which has proven very useful for squealing Shamrock tape. Thanks!
