 VCR4500 SANYO Service Manual by Thomas Christoph;
This is a top quality manual. You couldn't get better if you had the original and scanned it yourself. Best price on the net as well. Diagrams are clear and complete, text is sharp and easy to read. Granted you don't get the manual the second you click pay, but the few hours you have to wait for it to be available for download isn't a problem at all. This is a very reliable company. Very VERY pleased with the product, and will buy others. Thanks!

In a word AWESOME. I never expected the quality and abundant content that I got with this manual. Everything you'd ever want to know from a service perspective is found in this manual, along with... as a bonus, operating instructions on how to use the unit. WOW. Very impressed with the quality of the manual. You won't be disappointed if you're looking for the EVS900 service manual.
