here what my plugs look like....standard soundprofessionals and microphonemadness plugs.
Thank you for posting the photos.
NO problem picking the right-angle plug as likely innocent,
but that dual cord straight plug definitely looks like an R-09 jack killer
especially if used in pocketed or in-carrying-bag stxxlth mode
where giving the cords few even minor
tugs is unavoidable.
And this is exactly what breaks R-09 not cemented firmly enough
So I'm now thinking adequate glue-down, was NOT done
on your most recent replacement.
Being somewhat an optimist, might also be Roland is recycling 'supposed to be jack fixed' refurbished
decks from older runs as replacements, and you have yet to try Roland's most recent jack fix?
Same NOT GOOD ENOUGH credit
goes to Roland either way, even if your replacement deck is not most recent version.
Since it seems you're on a roll
and have a 'dialog'
going with Roland service
maybe keep returning the broken R-09 untill either getting a more solid fix, or a full refund
Actually getting a manufacturer's product refund raises a special kind of corporate flag that's way more noticeable than repeated service fix cycles, and losing sales cash helps gets across a louder dissatisfaction message.
And you get 'all your money' back instead of trying to sell used for less.
Suggest getting by using another (the back up?) deck when the R-09 is out traveling like a ping-pong ball back - forth in play?
Please post what's happening, especially
if deciding to play more
rounds of R-09 'table-tennis' with Roland
