Hi all,
After having repaired many faults in the power circuit and replacing the "normal parts" (mute relay, backup battery) the only component left broken is the power relay.
I haven't seen them being broken a lot, but probably due to a failure in the 7V circuit the relay coil burnt through (or the other way around).
It's the 4PDT 12 + 2 pins relay (RL1 on PCB60).
Tried already many sources, but it seems this relay is becoming obsolete / old fashioned etc... Not in stock any more (tried Tyco/Axicom; Farnell; RS components; Siemens and Panasonic).
So any one here has such a relay by any chance (or a good source/hint?).
Thanks a lot!
