So the resonance pot failed I think. I tried fixing it but no joy. :(

Now I'm having a really hard time finding parts. If you know of a parts supplier that'd be great!


Anyone out there got a 303 with any experience with this sort of thing?

Yeah I have a email sent their way. The part I need is out of stock. Hoping they plan on re-stocking.

There is a Vintage Repair Shop in Austin that's had a lot of great reviews.
Thinking my 808 will land there sometime in the future.

Almost sent my 106 to SynthSpa til I read on Vintage Synth there were a few Juno on their table for well over 6 months and then a sudden move from Nashville to Wisconsin.

You should definitely register on vintage synth.com lots of cool peeps there.

there is an eBay store from Italy, where a lot of early to mid 80s Roland parts were made. EBay is a gold mine for vintage Roland parts.

Thanks for all the replies!

I spoke with someone at https://syntaur.com/ and they don't expect to get that part anytime in the future.
So I went ahead and ordered a set of pots from some place in france (soundtoparts) on ebay. No way of knowing how the fit will be until it arrives. So crossing fingers!

Thinking I might try to get all the replacement parts for the unit now while they are available. Get it in working order, pack it away, and by a clone.

Yeah I did, but thanks man. Very Appreciative.

The little plastic (for lack of a better word) rivets?,... marked in the picture here broke off and the metal piece was just floating around in there, doing nothing. I tried repairing it, but meh.

I 3d printer would frickin cool if I had an accurate model of the part.

Thought I would give an update for anyone interested.. And also I'm so happy that I need to share, ( lord knows my wife doesn't care.. lol )

I ended up purchasing through a company "sound-to-parts" from france on ebay. Replaced it tonight after dinner and all it good. *pheeew
So my plan is to get as many replacement parts for it like buttons, dc jack, etc. now while they are available, put it in the closet and possibly buy a clone if I end up finding myself needing a hardware 303. Doubt I will ever get to that but..

kk, thanks again for all who helped.

good to know, and old mate offered to loan me his 303 as its currently gathering dust in a cupboard, he suspects there could be some corrosion where the battery connections are, im yet to take a look but this might be a useful service if it needs any new parts ;)
