I have a AV Mod board from Electronic Sentamentalities For the 2600 and SVA II..There was install instructions when I bought it but it's not for the board I have with contrast and brightness controls. So now I have 4 TIA connections from the mod board that are connected at cr15, cr14,r20 and r22 but have no idea what TIA connections go where. There are no Schematics for the SVA II and the instructions I found don't match my board..Anyone out there that has done this install ?? The connections are marked as tia2 tia5 tia7 tia8. Already have tia6,9,12 and 13 connected to the bent out pins on the Tia. And have s-video comp and audio connected..
