Hello, you are looking at a *** JBL Model 6230/6260 Power Amplifier Manual ***

This came from a musical repair shop that has been open for the last 28 years.  Please see my other listing for equipment and manuals.

This is an ORIGINAL PHYSICAL DOCUMENT, not a photocopy, reprint or digital version. There may be some wear & tear since most of these are decades old. 

Tech's notes are occasionally written inside the manual, they are usually helpful hints and tips or prices/etc.

If you have any questions or concerns, please call or text at (TWO-03) 313-9396.

Thanks, Rick!!!
