Cheers Philip+!! Got 4x of these old expansion boards to do tonight, as my Panasonic 100uF, 10V SMD caps just turned up - happy Lockdown!! Be safe .... 🖐😷🍻👍
Hi Arrayzable. It was not the most stellar soldering job I ever did (I might consider buying a hot air gun next time I encounter this type of component), but it was a nice experience. :) Thanks for stopping by. Cheers!
Hi carriersignal. Thanks for the advise. I brought one since... I used it for assembling a PreenFM, and worked like a charm (after some fiddling adjusting my hand positioning while soldering). Cheers!
After recently purchasing a JV-2080 and a Session expansion board, I feel like I wasted my money. I feel like I have to do this on my own but I'm not sure if I can.
If you are unsure, you might want to reach out to a local electronics club... Most universities and colleges with a degree in electronic engineering have IT clubs with tech savvy people glad to help you out... Maybe even teach you a bit on how to maintain your gear
He he he. Nice comment, Ludwig, but I was really concerned my JV1080 would be damaged by an exploring capacitor (it is my work horse). Have a great week! Cheers!
Essentially, all electrolytic capacitors have this problem (this is also why people re-cap the power supply of their older hardware). The electrolytic media inside the capacitor corrodes the cap of the capacitor, leading to leakages and eventually damaging the pcb. Of course with each new generation of electrolytic capacitors, the durability (usually) increases.
@@Philipplus thats not true, to the extent that ALL caps in ALL electronic equipment would have to be replaced of its over 20 years old.. not so, i have lots of stuff, ham radio etc over 30 and 40 years old with no bulging caps etc.. there MUST be a bad batch of caps in these roland cards.
@@RobBob555 I know good quality capacitors do last a really long time. If I'd have to guess, I'd say that somebody cut some costs somewhere in the supply chain. I'm also leanning to your point of view, considering my JV is older than the expansion boards and even the large capacitors in the psu are fine.

Thank you. Just be careful removing the caps (I went a little bit to harsh on one of them).
Be safe!
Great job. So satisfying when a soldering job is done and everything works!

Thanks for the upload. Get a Panavise dude, it'll make your like a lot easier.

@@Philipplus I’d rather do it myself. 😑
@@Philipplus How do you desolder the legs? mine broke just like yours did.
@@ecclesoul I later learned to use very fine and good quality desoldering threads.
@@Philipplus desoldering threads. you mean the wick?
Wow. Pimp that synth!!

Cheers!
Philip+ sure thing. Hopefully the patient is doing fine.
The patient recovered graciously. ;)
Philip+ oh thank God. Philip is happy again. And we can celebrate with a good soundtrack.
😄
you would imagine roland would have a specific date for affected boards.. i CANT be them all.

You just twist them off with pliers
