Hi,

Here is a link to the service manual for your amp.

To download the manual, when the sentence below the Document preview box changes from This file is downloadable free of charge: ...processing... to This file is downloadable free of charge: Get Manual, click on the Get Manual as this is the download link.

Be patient. It takes a little while to find the file.

If it it only affected when the drive select switch is operated, check the circuit around the U2A / U2B amps section. (make sure you're looking at the 15R cct and not the 15G cct).

Hopefully this is of some help
