Reported as problem with guitar input socket, owner tested with 2 leads
and 2 guitars, and amp problem. But of course no problem with me, as
received and now with the thing dismantled , including the Tx , to
reconfigure under power and rattle and bend .
Yes PbF, but i/p socket solder points look ok under x30, and trying to
force signal contact pin out of the pcb with circlip pliers acting
between pcb and protruding lump at axial end of the socket, just flexes
the pcb.
Anything other than wiring in a replacement conventional socket and
bypassing a tiny via, in the signal line, and crossing-fingers against a
bounce? Plenty of tip contact clearance in open position.
The phosphor-bronze pcb grounding contacts do not constitute a ground
line through the amp casing.
