Should be simple 1/4 inch so. S/R bypass sw. fixing, but for removing the
main board.
I ended up graunching off the speaker cable clamp as it is inserted from
the
inside , not the outside and simple mole-grip compression job to remove
it.
(note to myself, next time confronted with this situation, try a small
driver between black plastic retaining tongue and the hole in the steel
and
push inwards on plastic bulk, may work but not tried)
A plain grommet will be going back there as wires are loop-through
anchored
plus solder to the pcb only 1.5 inches away anyway.
How on earth did someone assemble as no clearance space, you cannot even
see
that area as surrounded by transformer and heatsink and casing. Just
referring to the heatsink, made me realise they probably assemble board
without LM3886T h/s and that goes in last. But then I would expect a
couple
of holes in the rear of the casing to facilitate screwing on , would need
some sort of miniature flexible shaft or right-angle-drive screwdriver to
tighten
Maybe the mains transformer goes in last, but very short wiring loom to it
and still you cannot see the speaker thru-hole area and awkward bent
finger
tip insertion.
Anyone else confronted with this conundrum ?




I've replaced the LM Power Amp IC on several of these. The cable clamp
grommets were on the right way round and no doubt fitted last, as thats the
only way they will go on.

Maybe the aliens did it. Or its some kind of Chinese assembly line joke.
