I have a manual that could be of help. I can also answer most questions for you. Also, go to the Joule website. Under reviews there is one on the LA-200 by Bob Sireno of PF. Bob reviewed and bought the very first LA-200 and I bought it from him when he auctioned it off last year. I have since upgraded it to an LA-100 MkIII per Jud's recommendation. Email me with your questions and if you'd like a copy of the manual.
