    I just picked up a few things from Mouser from your list. I'm fixing my auto stop and up/ down button issues. I already recapped this unit and cleaned lubricated the spindle housing. Thanks for the professional and thorough rebuild info. Very impressive.

    Is it ok to cut the ends of the thyristor shorter so it doesn't sit so high in the board or should I leave the legs long and solder it the way it is? Will cutting the legs shorter affect the switch?

    Yes, but before you do, I would use the old/original component for visual reference to see how long the leads were, then solder the new one into place and you should be good to go!

    No, but you do want to take care not to trim the leads to close to the terminal board. Ideally, you want them to extend out past the board a little bit to ensure a good solder joint.

    Does anyone know where I can pick up the LN25 LED that works in conjunction with the photo darlington?

    LN25 is an obsolete part.

    LN28RPX from Mouser would work however.

    This is a round LED, right?. Is there a rectangular one available from Mouser that would work?

    Yes, but they don't have the domed shape end on one side like the originals did, so I went with LN28RPX since it fit the eyelet hole.

    Anyone have a source for these red LEDs? Working on a 6300 now that has the infamous issue with not shutting down. Im ordering a new optic sensor as well but seems Mouser has the LED listed as obsolete.

    Ive tried searching through mouser for a replacement but only came up with the Dialight 560-0104F which has no datasheet. Figured Id ask before taking the chance. Id prefer to stick with mouser if possible as I have a cart saved for some other projects.

    I took an ordingary red LED and bent it to point at the sensor - worked just fine.
