I ran 220v through my 110v tr-909 :(

[disco judas]

I guess for about 3 seconds as a pulled the plug out after 909 making noise.
Do you think I may not have give it damage?
I did not see any smoke but maybe smelled I tiny bit something from it.

Thanks

shit Shit SHIT SHIT SHIT

Does it still work? If not the good news is the parts have value

[disco judas]

puhh - it works

and this is a very nice condition 909

but all the gain knobs start crackling when turned to a low volume, but
this may be beacuse it has not been turned on for a couple of years?

Not to come off sounding like an expert but it is probably ok, dunno how the powersupply looks like but the components in there are the ones taking the hit and if it's got regulators those would be the first to blow.

But since everything is fine you got lucky!

[disco judas]

cool,

so either its blown or its okay - nothing in between.

It felt like it was plugged in for about 3 - 4 seconds, but it was probably between 1 or 2 seconds

[Resonance5]

wow mate that was close

[sameal]

thank the audio gods for your cat like reflexes and never do it again.

Ohhh

They sound crackly and noisy when tweaking the knobs though,
anything I should look for when opening the unit?

give the outside a good clean first (not with the heavy duty fluid - just mild detergent)
turn it off of course
then work the pots a couple of times - it's dust
if that doesn't help - invest in new pots
lubricants like deoxit are a quick fix

Might have given it a bit more 'warmth'

[TRANQUILO]

thats hot

The Geekslutz would be able to tell you if you damaged your beloved TR909

If it turns on, its ok, when it comes to this kind of screw ups, the power supply is the one that melts down, but yours seems to be ok.

The crackling sound on the knobs is dust accumulated during the years, you have to open it up and spray some Caig deoxit in the pots, then turn the shaft back and forth several times, problem solved....

Done the same a couple times (moved back and forth between Europe-USA-Europe), a Yamaha QX1 Sequencer - some pops then white smoke and smell. Some year later a Behringer ADA8000 - some pops no smoke but smell.

Is this always the case, as a rule?

Well no, its not a rule, but dont be anal about it, its probably ok.

[Analog Prophet]

Yes, if it power up it's no problem. If not, it´s probably "just" the power supply that is fried and that is not the same thing the the whole machine is out.
