I have bought two Eckmiller W86a eq moduls some time ago. I thought I could use them as master eq but attempt and no sound through them I looked into the schematics and found out that they need some kind of a preamp.
Therefore I desided to build two API clones and put them in the case as well. I found a schematic a friend had modulated and modifyed to my needs.
I am using a LL1528 input transformer and a Cinemag CMOQ-2S output transformer. As for the DOA I was so lucky to get two Jensen 990 from the same friend who helped me with the schematic. I have also removed the 48v option.
Then I tried to draw some PCB layout but I'm not sure how to put the ground link around the board.
Someone here that maybe could help me looking into the layout so I'm absolutly sure that it will work.
Cheers
