Ebay Roland DEP-5 Relay & Battery Repair DoItYourselfMusician #42

Thanks for making these videos! I'm working on a DEP-5 as well. By the way, as far as the cr2032 batteries with the offset pins go, those are the ones found in Yamaha DX-7 synths and some of their rack units. I've lost track of which units of mine still need new batteries... One of these days I just need to solder in battery holders for every single one of them! I already put one in my DX-7.

Many thanks for this video. I have a similar problem, and have just ordered the replacement relays for my DEP-5

I was about to open mine to check the specifications for the corroded relays. This is good timing, thanks and best regards

Great video, but I do have a little concern with the power dissipation. Running a 360 ohm coil with a coil voltage of 15.6V~ would result in power dissipation of about 670mW, greater than the recommended 400mW power rating for both the original (DS2E-M-DC12V?) and modern alternative (G6A-274P-ST40-US-DC12) relay. I wonder if this excess power is contributing to the common failure of the relays in these units? Could be mistaken. After some searching, I've found an 18V relay (RY-18W-K) which will switch at 12.6V, it has a much greater coil resistance of 1.62 kohm. Using this relay would result in a power dissipation of 150mW which is within its spec. Note I haven't tested this relay myself yet.

I need your help! I replaced the relays and I have no effect. I have output with a slight buzz but I don’t hear the relays kicking on. I bought it off eBay as-is thinking it would be a simple fix but doh🤦 I’d like to pay and ship it to ya and have you service it and bring it back to life if possible!🙌🏻 thanks for you’re time and consideration 🙂

Hi all. I just recovered my DEP-5 that had been stored more than 10 years in an empty house. A friend of mine could repair the battery as well as some faulty parts, but it seems that all the "sounds/settings" have gone. Is there a way to copy the data thru sysex import, and if yes, where can I find the data? Thnx bunches and Happy upcoming year!

[@tokenofdevotion]

Were you ever able to replace those jacks?

[@GelexTP2]

How is the output quality is it clean and powerful?
