SR-JV80 expansion cards - exploding caps!

Unread post by Rara »

I was searching for a couple of expansion cards for my JV-2080

I haven't seen a post about this on here yet.

I came across another forum with links back to Roland Japan
informing users of a potential failure of the capacitor on the
expansion cards

The capacitor should be replaced ASAP. It was also suggested not
to use them until caps were replaced. it is a 6v cap and should be
replaced with a 25v cap.

If any one has these in there synths search for
"SR-JV80 expansion - risk of capacitor explosion"
you should find the page easily. Have those caps changed
before any thing like this happens.

Well - afaik those cards are running at 5 Volts but some cheapskate thought that an electrolytic cap designed to operate up to 6 Volts should be good (and cheap!) enough - but it was NOT!

A good quality cap with 16 Volt max. operating voltage should be also an appropriate replacement...
