Orange Rockerverb 50 MKII schematics needed

[Zouto]

Hi, to fix a seriously humming Rockerverb 50 MKII (2x EL34, 7 pre amp tubes) with damaged Reverb circuit I need its schematics.
I got the (different) schematics of the MKI with 4x EL84 and 6 pre amp tubes, but could not find the MKII ones.
Thanks for help
