    Im just wanting close up pictures of the board itself.

    My board unfortunately as it turns out has resistors etc for 110v, not 240v.

    Im wanting to see the differences of the 240v ones to see if I can modify it.

    Any help would be much appreciated!!!

    Did you ever find a picture of 240V ones Shell as I currently have some here that were sent to me for repair and there doesn't appear to be any info anywhere on what resistors should be on the 240V CTB32LD boards. The 150k that are on them now melt off at 240V.

    Below is a photo of a CTB32LD that is properly configured for 240V (and a 110V one damaged by 240V). There's a whole bunch of variations to the 110V ones.
    These include
    -power jumper set for 240V
    -optocouplers U1, U2 etc (16 of) MOC3052 (110V has MOC3023)
    -R75, R76, R78 & R79 30k (110V has 15k)
    -R3, R6, R7 etc (16 of) 120k (not sure if 110V has any installed)
    -R1, R4 etc (16 of) 2k2 (110V has 330R)
    I didn't check the triacs to see if they match
    There may be other variations
