As mentioned in the article The Technology of the Tube Screamer by R.G. Keen (http://www.geofex.com/Article_Folders/TStech/tsxtech.htm):
"In the TS 808 and 9, and probably the TS10 as well, the external DC adapter connector is prone to crackling either the solder or the board where it's soldered on. This can lead to intermittent operation of the unit, as the normal battery power goes through there as well. To fix this, open the unit up and examine the power jack and board immediately around it. If you have solder crackling, remelting the solder with a touch of an iron and a little fresh rosin core solder will fix it right up.
If the board itself is cracked, just remelting the solder will temporarily fix it by bridging over the crack, but solder is a very poor mechanical material and it is likely to crack again through the solder. In this case, use a bit of resistor lead on the tracks, bent to shape and soldered in place for a ways back from the connector leads. "

| The board is cracked (the screw holding the board to the enclosure was too tight?), but the traces are still intact. I realized it when I plugged the power adaptor in the pedal: the dc jack went inside the enclosure... There is still enough board for the screw to hold. I just added a drop of superglue. Not moving anymore. |
