[sdiy] Roland RV-800 anyone?

[mark verbos]

Hi all,

I have a Roland RV-800 that needs a little help. This is a spring reverb unit that was only sold in Japan. https://www.vintagedigital.com.au/roland-rss-rv-800/
It seems that the signal routing/switching is done remotely, using the panel controls to send gates to analog switches or FETs or whatever. When mine turns on it is stuck in no man’s land where no signal passes and if I flick the switches a few times it comes to life. I’d love to fix it, but I have no idea what’s in there.
