    so it works fine but no lamps
    well 1 lamp the pointer is lit
    i have 6.5v across all fuse lamps but no light
    but with out taking it apart further, i have continuity across all fuse lamps while still mounted
    does this make sense?

    i'm outta time right now, i guess i have to pull the bulbs and check individual?
    i did clean the selector switch waffers.

    Look at this.

    Note that there is a path to ground (continuity) through R079 and the filament of PL009. You would read continuity across the lamp sockets without any lamps installed.

    This may or may not address your issue.

    General information. Check voltage on the contacts of the lamps and not just on the sockets. There may be bad connections between the lamps and the sockets that will not show up if you measure at the socket contact. Remove the lamps and check their continuity.

    thanks
    the tiny resistor on the back of the waffer is the cause

    PL009 is the dial pointer. You say that's working so that resistor has to be good. If you have 6.5 volts AC at the lamp holders, the switch is good. It looks like either the bulbs are burned out or not making good contact in the lamp holders. Dial lamps should be on when AM or FM is selected and off in all other positions. For good measure clean the switch with contact cleaner followed by deoxit G5.

    Please post the serial number for the database. Click on the link in my signature block.

    every single light is burnt, except the pointer
    going to convert to led, will mod so the dial lamps stay on, and function lamps still switch.
    i have lots of sui will start adding the numbers

    take it this one is Sept 1970

    It looks like there is a digit missing on the serial number. It should have 9 digits. Can you take another look? Thanks.
