If the ghost is 1.8 seconds (1 min/33 rpm) before the correlated signal, then the record pressing is at fault. If it isn't, then tape mastering is probably the culprit. Most cases I've seen are caused by tape mastering (in fact, they usually are re-releases of older performances which have probably been archived on tape for several years - the tape blead-thru problem gets worse with age). Of course, depending upon the diameter of the tape reel, tape ghosts could also be delayed exactly 1.8 seconds. This is unlikely though. ------------------------------------------------------------------------------ The greatest derangement of the mind is to believe in something because one wishes it to be so - Louis Pasteur James Giles
