Could someone please help me with the proper wiring of the OT, jacks and speaker of a 70's pcb SB-12. The way i got it there are only two wires coming from the main speaker. And the black is ungrounded It's soldered to the est. amp jack's switching lug which has the tip terminal snapped off. this looks fatory but i'm having trouble with oscillation turning the treble control ccw. and lifting the negative feedback doesn't raise the volume it actually lowers and distorts more.
The OT IS the replacement from fliptops.com
Any help from someone who has an original like this one or can help from the schem is much appreciated. i've been stuck on this project for years
thanks
i tried to attach a pic of the wiring as is but file too large. tHis is the 6l6 version btw
