Very dumb question I'm sure.
« on: February 25, 2019, 09:11:34 am »
I am probably the only person on here who has not seen or played a 65 DRRI. How the heck do you install this board in the amp when the pots are turned around backwards? Here it is below. Just kidding but why is it drawn that way?

The boards were manufactured as a single board. Much easier to make the board. Then the two boards are snapped apart. Look close and you will see where the snap-off tabs are.
A schematic, layout, and hi-rez pics are very useful for troubleshooting your amp. Don't wait to be asked. JUST DO IT!
