    VR411?

    No. From what I've seen in postings, the range is about 11.5-12.5 for this model supply.

    Found some 1n4148 in the parts bin. I'll have to cut a trace and tack on some fine wire to insert them. Will post a photo if successful.

    R419 would change the range of VR411.

    Good Luck. Please post how the diode trick works.
