  • Deluxe Reverb Rebuild need expert help

    Hi - new to site. I'm rebuilding a silverfaced deluxe reverb with the drip edge. It appears to be an AB763 judging by the resistors over the 6V6 tubes.

    I've got the layout and have put the parts back that were missing. I have an issue that I can't understand. There are 5 16uF caps monted under the chassis - these have yellow leads coming up from into the chassis. I've got two leads coming out near the 12AX7 and one goes to resitor node w/the 10M etc.
    I dont know where the other lead would go.

    Any suggestions would really help. Thanks in advance.

    Look at the schematic and see how the filter caps relate to the B+ supply. Then hook up the caps accordingly. (Hint - the +ve ends of the filter caps will all go to somewhere or other in the plate supply circuit after the rectifier and before the plate resistor(s) to the pre-amp plate node and PI plate node, with a couple on the node of the OT primary to the Output Tube plates and another one on the screen supply choke node (before screen grid resistors) to the output tube screens.)
