JVC HR-S3800U Service Manual page 19

Note: This table shows the order in which parts are removed for replacement. To replace parts, remove them in the order of
1 to 18 as shown in the table. To install them, reverse the removal sequence.
The circled numbers (symbols and numbers) preceding the individual part names represent the numbers in the "Lo-
cation of major mechanical parts" table. Also, the "T", "B", and "T/B" on the right of each part name shows that the
particular part is removed from the front, from the back, and from both sides of the mechanism, respectively.
