Mods/repairs to CEC TL-51 belt drive transport?

I have been using a CEC TL-51 belt drive transport for many years. Time to modify! Bulit like a proverbial tank, it would be a shame to have to replace it. Does anyone know who works on CEC transports? Laser replacement, capicitor upgrade, etc...
Nick Gowan at True Sound in Northern, CA. is the US service center for CEC so perhaps contact him for advice.
