Reply to Juniper's question in "test bench"

For some reason I'm getting a database error when trying to access the "test bench" thread!

 

Pat, although I don't have your picture, here's a link to one of the underside of the same amp:

In your case, the adjustment pots are mounted to a metal bracket (see the right side of the picture), so when the screw driver slips you are simply hitting that.  However, it's always a good practice, when adjusting controls which allow tools to go inside the chassis, to use a plastic or other insulated tool.  Click on this link, and then click on data sheet:

It's a good idea to have a set like this available for making adjustments.  An alternative is to get a 3/16" or 1/4" wood dowel and shave down the end to create a screw driver blade of appropriate thickness.
