Re: Noria power cord adapter question
I recapped two similar, slightly better units yesterday.
Ripple before was 1.4Vpp, yes 1.4 volts.
Afterwards, it was ~300 mVpp.
Load was 1.4A in both cases. The original output cap is nearly useless even when new.
Caps:
4.7u 200v Nichicon VZ
47u 16V Nichicon PW
680u 25v Nichicon HE
The output rectifiers were 3A devices, so I left them. No fuses, of course, so I installed some fusible resistors from a TV. The boards had space for them.
