Dear all,
I'm recapping the non working PSU of a LCIII.
I checked the optocoupler[1] by testing pins 1,2 which correctly shows a diode.
But the 4, 5, 6 does not show a NPN transistor, so I assume it's bad.
I'm not able to find it or any equivalent PS2561-1/PS2501-1, NTE3041.
(I am waiting for the new capacitors, so I can not test the PSU with the original PN111)
Can some electronic expert advice on what can I use?
thanks so much
