Sony PS-X70 Owner manual needed

PS-X70 Owners manual

I'm looking for one too!

Sony PS-X70 Owners manual- (Manual operation & faults)

I am looking for a Sony PS-X70 Owners manual just for collector sake.
As my TT is working ok here are a few hints that may help ..

Basically these are studio turntables to be used a lot . If you have them sitting around for 12mths of more like i did then the Manual or Auto lift , start don not work or are slow . I have found that a spray of WD40 or oil on the arm lift /lower shaft helps to free it up after several orpertions .
This appears to effect a lot of functions. including the auto return. Mechanically helping the Lift lower with you hand after spraying .All this should be done with the start/stop led light "ON" only all other lights "OFF"

Hint , I use the TT in manual mode only start/stop led light "ON" only in this mode the arm auto locates the beginng of the record and auto lifts at the end and should return to the arm support.

Be patient this can be slow .

PS-X70 manual

I have figured out how to work it manually (no pun intended), but the auto functions are rather idiosyncratic, working sometimes, not others.
Great sounding heavy duty machine.
