It has been replaced.  The 33-45 needle was worn out.  The tone arm skated across the records.  But not with a new needle.

I used two fruit crates as a work support. The power computer speaker was a convenient monitor.

This will be replaced.  I want no failures once it leaves the shop. 

  IMG_4116.JPG (723822 bytes) Old, hard and sanded smaller. Will be replaced/rebuilt.  

 

IMG_4121.JPG (277871 bytes) Unfortunately, this pulley was gouged and too small.  The strobe showed a slow pattern with the new belt installed.  I suspect some one tried to convert the turntable from 50 to 60 Hz.  

So with nothing to loose, I used automotive body putty to build up the shaft.  I started to trim and shave the shaft to a convex shape.  Use the motor to spin the pulley.  I need to check the speed with the new idler wheel before filing any more. 

If the putty does not work then on to metal filled epoxy.  If that does not work I will look for a new pulley or have one turned.  The black tube is a shop vacuum cleaner to catch the putty dust.

The Bondo (auto body filler) worked great!  

These are the vendors I ordered parts  to rebuild this turntable.  

You can benefit from my hours of research and emails.  

FBL6.6 Flat Belt, Large 6.6 Inch

This is the new belt I ordered.

The mount needs some "customization" to fit the head shell. And it is a tight fit. Sounds GREAT!

I sent the idler off for rebuilding.

And the rebuilt one works GREAT!

This is how my PE4230 is wired (A to B).  Ignore the C contact. The 160 volts is derived from the primary of the multi voltage power transformer.
