inside MXR dynacomp!!!???

[Jay]

Hello
I need to see some pictures of inside of a MXR dynacomp from 70’s.
From the pcb and the switch and all.
If you have some pictures please let me know:help: .


Thank you all in advance

What do you need to know?

I need to know where to connect 3 lose wires

Orange yellow and gray are lose.

Jay,

I've got mine open in front of me (pots up, PCB standing straight up). The orange wire runs between the far-left terminal of the left (Sensitivity) pot & the upper-right solder blob on the bottom of the PCB, and the gray wire goes to the center terminal of that same pot & the lower-left solder blob on the bottom of the PCB (no connection to the right-hand pot terminal). The yellow wire runs from the same Input-jack terminal the other yellow (switch) wire connects to, to the right-center solder blob on the PCB bottom. For reference, there's also a brown wire from the upper-right of the PCB to the switch.
Let me know if you need the PCB connections and/or a pic (which I can E-mail to you). My unit is red, w/lower-case 'dyna comp' lettering.

Thank you

Jay,

No problem at all - glad to help. I'm actually happy I opened mine up, as both the box packing foam and PCB-insulating foam were quite deteriorated, and the battery was nearly dead! I better check the other ones now too... :)
