series loop mod

[rectofried]

i tried the search function and everything under the sun came up but what i needed. does anybody have a schematic or pics to perform the parallel to series loop mod. on the rectifier?.. i sent my amp to a tech and he was suppose to do it along with other repairs but i guess he forgot and shipping is crazy,so i want to do it myself.

It's very simple - just remove the wire from the counterclockwise end terminal of the Mix pot. You can move the wire from the center terminal to the clockwise end as well if you want to be really thorough - otherwise the Mix pot still affects the return level (although this may actually be useful).

If you have the chassis open and the back panel is closest to you, and the pot is with the terminals pointing upwards, it's the right-hand end you need to disconnect.

i have an orange on left red in middle and green on right..on the mix pot. (from behind flipped chassis).
so i need to tie off the green and move orange to the middle prong with the red? sorry for being simple minded here but dont wanna screw anything up. what about the jumper wire between the send and mix pots? disconnect that as well?
