http://i43.tinypic.com/9u1z12.gif Above is the pic of my driver board. The 2 resistors I used in biasing are the gold gold white orange resistors. I put the arrows at the legs that was giving me what I thought were the proper readings. I just found it odd that the legs that gave me the readings of 37 and 25mv(after trim adjustment) were on opposite sides! The other legs of these resistors gave me 1.8ish each. Does this seem right? This amp was in rough shape and I stripped it down completely! After doing this bias(which I hope is correct) I plugged in before buttoning her back up to hear what I had so far and it sounds pretty good. I am also trying to dial in the reverb/trem but I am having issues. I didn't take pics of this before the tear down. There is an output and input jack on opposite sides of the reverb pan and 2 inline rca jacks on the bottom of the head. One sits towards the front and the other towards the back of the amp. Which way do the input and output of the pan connect to the inline rca inputs on the underside if the head? After I get that, then I have to correspond the red and black from the footswitch to the back rca inputs. All help is much appreciated!! I just added to this post and I hope this doesn't double post. If it does..sorry!  | ||

The easy way is just plug them in and try. If you have them backwards underneath, the reverb will be very weak, almost non-functioning. Just reverese them-no harm. On my 65, the red connection is towards the back of the amp. The pedal should have one red connector and the amp has a red dot to the left(from the back) which is the reverb. Now that's a 77-8 65 with tube driver but I can't imagine them being different until you get to the rp's and rd's. |
