my power switch seems to be broken and the OP-1 starts up even in the Off position and crashes itself until the battery is empty, works fine when turned to On.
iam looking for a spare connector board just to re solder the power switch!
if you have one with a broken mic or input output jacks iam highly interested! 
have u tried cleaning hte switch yet?
might just be dirty
has happened to mine a few times.
cleaning it was all i needed
a lil deoxit works great
yap? I have some deoxit here but thought that’s not the right way with this switch!?
but for future situations iam open for a spare one! :))
worked for me. deoxit works on pretty much everything.
for best application u gotta pop open that bottom plate to expose the connector board
and get at the actual switch behind the switch cap
if u spray from the outside, it doesn’t always get inside the switch mechanism to clean up any dirt/gunk that may have built up
i can say it feels like new after deoxidation and it’s a day & night difference between sliding the on off switch or clicking it into the position like it is supposed to.
pro tip
nice! glad it worked out for u… saved u some bucks 
yea i had to do it maybe twice a long time ago and haven’t had to do it since.
woke up and the OP-1 was awake, too! 
so it feels better but it has not worked at all.
i guess I have to wait for a spare part
JohnnyEgo, literally just changed my connector board as the line-in on my previous one had broken, though I feel it could probably be fixed with a little delicate soldering. You still after a connector board? I’m in the UK by the way.
yeah great!
iam highly interested and would love to receive yours if possible.
at least it’s flat enough to be shipped as letter.
DM incoming 
rats!
u could always try spray again. might have been real dirty?
did u work the switch back and forth for a hot minute after u sprayed?
and/or u could try to reflow the switch joints?
both! I’ve resoldered the joints to make sure the switch is a dully. Unfortunately it is and also made sure that i‘ve sprayed it twice. 
ifixit stocks OP1 parts.
I had to replace my board when my input jack wouldn’t switch to line mode. Took me 5 minutes to swap it out…
yeah that’s great! as some people mentioned they‘ve changed their boards Iam looking for the unused broken boards to de solder the switch to my board.
what about yours? :))
Long gone buddy. I’d send it to you if I could…
i’m just gunna leave this here…
