I just bought a 5B10N on the auction site that looked unusual. It has a toggle switch in the upper right corner of the front panel labeled "L vs R (BLANKING)" and it appears (from the images included in the listing) to have a factory mod called "Mod 711C", but I can't seem to find any documentation about such a modification on TekWiki. Does anybody know anything about this modification and what it does?
I have posted two images of the item (images from the listing, since I have not received the item yet) in the album
