It looks like Tom might have implemented Grahams frequency divider mod too, a second clock that runs the Pioneer display circuits causes a measurable problem in these players, not well known, there's a pair of wires running that way. I did this on my 703 but I have lost about a million brain cells since then so I dont remember much, I cant remember if the second crystal was on the display pcb or if it was in the position where those cables run too, I wouldn't buy another one of these players if it hasnt been done, just couldn't sleep. LOL
