I recently rescued this seldom-seen STUDER A-810 trolley in nice, used conditions which previous owner was keeping in his kid room 😏 - I took off the speed vario and monitor from over-bridge, cleaned and tightened all hex-nuts and screws… in a couple of days will add a missing screw, some chassis missing plugs and an accessories shelf to the emptied VU-meter bridge… almost ready to get my trusty STUDER B67VU in a more compact package.
