Quasimidi Sirius Repair:
Quasimidi sirius repair:
- A broken keystop
- Non functioning keys,
- Sequencer issues,
- Sticky buttons.
It needed a complete overhaul. We found gaffa tape that had dried out and left a mess over the battery and ribbon cables, many minor issues that needed sorting out as shown below.
The unit had been working off a 9V 1A power brick which seemed rather odd as the internal 5V regulator should see at least 10V to operate correctly. Anyhow this was replaced after bench power testing had it running on less than 9V ?
Work done:
- The snapped keystop was solved so the key actually worked again.
- Key contact strips cleaned.
- All potentiometers replaced.
- Repaired broken EPROM leg to socket.
- Buttons cleaned.
- Keys cleaned.
- Rust treated.
This thing is a small beast monster of a synth.
