I still think one of those components (CR1539, CR1534, C1537, Q1544) is leaky.
ESR test and diode tests were not accurate enough to identify. As a last
resort you can replace them all. You can start with diodes and cap, if it
doesn't fix anything, replace transistor. Cross references are in:

Note that the diodes have very low reverse leakage spec so a random diode
won't work.
Thanx Ozan,
Will replace those components - I need to make some purchase so probably back on the air after a couple of weeks...
