Help! info on RM ric comp/Tbooster circuit

[john]

I am trying to get in contact with Mark T, who posted here before about a circuit that emulates the Ric RM compressor/treble booster; he stated that he had built one into his Vox 12. I am trying to get information on this, his email from this forum bounced. Or if anyone else has a way to get the original Red Rhodes box..Or , if the guy Bobcat sold his spare original ric unit to would like to help out..any help with this would be greatly appreciated.
