One of the modification steps is to cut the jumper wire on the terminal strip between terminal 2 (center tap of 6AN8/EL34 filament winding) and terminal 3 (chassis ground). However, the modification instructions never tells you to connect terminal 2 to anything else thus leaving it floating above ground.
If you do not use a preamp needing power like the WA-P2, should this jumper be reinstalled? I am refurbishing two Mark IIs and one has the preamp mod and one does not. I will never use them with a preamp like the WA-P2, so should I reinstall the jumper, or does it matter?
