Hello all.
I’ve got a Defy 7 that needs some attention. Pls don’t ask me why or how
)). It’s working, sort of, but when I looked inside I found some problem areas.
1. All fuses were 250mA instead of 160mA, and one was 500mA!
2. One 180 ohm resistor burned, as well as near-by 1K. Both were cruelty replaced from the bottom side with large 5% resistors.
3. 4.7 ohm 10w de-coupling resistor between two banks of the large blue filter caps was removed completely;
4. Second stage filter caps (two 100uF@450v in series each channel, located at the very corners at front of PCB), were replaced with two 750uf photo flash caps in series!
I wonder if I should leave it alone (apart from replacing 180 ohm and 1K), or restore it to stock?
Any advice appreciated
