I added a new web page on whether or not a record changer is suitable to play your records without damaging them:
http://geocities.com/midimagic@sbcglobal.net/safchang.htm
Please check it out. Also send me a message if the page misbehaves on your browser (I'm testing some code compatibility).
Note that if all of you test it at once, my ISP shuts down my site for an hour. If this happens, wait an hour and try again. Do not report this as the page misbehaving, because the ISP imposes this.
