| Akai | CT2567 | St/by only | timing constant capacitor for the standby IC is leaky. The IC is mounted on a heatsink in the middle of the board. C093 is a pair of surface mount capacitors [in parallel] connected between pins 2 and 4 of the IC. Remove these capacitors and replace them with a 220nf. | 14-09-04 |
