I was lucky enough to be left a Fulltone That 80s Rack Chorus by a deceased relative; but the chorus effect on the right channel doesn't work, which im pretty sure comes down to this fried vactrol (there was a little residue on the board there that I believe was where a rat peed on it in storage, which looks to have shorted the vactrol).

It looks like I could easily swap it out, but I can't figure out the specs for a replacement based on the markings.
It says FULLTONE OPTO1 (or 01) 1245, and nothing else besides LED and CELL, as far as I can see. I haven't found anything that matches it via google, any ideas on how I can determine the right replacement?
The unit seems to work perfectly otherwise, and I'd really love to get it back to full tri-stereo glory. I've got some experience repairing electronics, but still got a lot to learn and kind of hit a dead end with this. I'd really appreciate any help or direction! Thank y'all!!
