I have a Marshall DSL20HR, I want to change the valves, do I have to make an adjustment when changing the power valves, or they do not need adjustment.
Thanks.
I was wondering whether, when I swap out the power valves, I would need to make an adjustment, or if it wasn't necessary. If you're still experiencing trouble after making sure you're holding down the'store' button, which, if pressed alone, would cancel the reset, ? is the address to write to for more assistance.
