Does anyone have chas_stevenson ‘s notes concerning Merida TEV550.

Hi, I have posted this in both Merida and General Forums. I am inquiring if anyone either has contact with or access to the modification notes created by a chas_stevenson concerning the Merida TEV 550 and/or its relatives. He had a web link and e-mail address ( chas_stevenson [at] yahoo.com ) posted in some Merida forums, however the link is no longer valid and there was no response from the posted e-mail address. I am hoping that someone has those notes and could share them, reply and I will share my email address privately, or perhaps post them to Visforvoltage in the Merida section. I am making modifications to a Merida TEV 550 and would like some guidance. Thankyou, Persona Non-Grata.
