ADA Preamps > Original MP-1
Anyone ever seen a mod like this?

This is my 3rd or 4th MP-1 and I was getting ready to mod it with the 3TM mod. When I opened it I found that it had already been modified but in a way I've never seen before and couldn't find in any of the lists of mods.
1) the daughter board has 4 TL072CP Op Amps
2) it runs from the rear and front inputs

Can you post some more detailed and higher res pics? I can see he disconnected the headphone jack and connected it to this board, I also see you tapes off the signal from front vol pot. It looks like 2 identical channels. But I can't see what going on with the back input, is it also disconnected? A long shot and in the dark but maybe a stereo effect loop? Just guessing here.
