Hughes & Kettner - Tube Replex - Mods

Hello,
Over a year ago I had heard about a mod for the Hughes & Kettner - Tube Replex - where you are able to cancel out the Dry signal utilizing a switch (SPDT i assume). The person talking about this mod would not reveal it due to wanting to market the mod over the internet. After months of harassing the wonderful folks at Hughes & Kettner. (a company with only a few US dealers is a mother to get a hold of let alone schematics for their products)!! I finally got the schematic!! Which i thought would be the gateway to taking on this mod. Well due to my own confusion i seemed to have stumped myself! Will someone please view the attached PDF and help highlight where this mod would take place. I am thinking that disconnecting C58 is a viable way to kick out the dry signal but am not 100% because of the 4053 switching IC. Thank you all in advance for any help! As well as take the schematic and save it, because believe me H&K aren't very willing to release these schematics.

old post, but....

it looks like ic5 is for the bypass. if you disconnect c58 you will kill your bypass signal. if you remove r32 (47k) you should be able to remove the dry signal.

thanks for the schematic. i'm looking to get one of these and it will come in very handy.
