Hi guys!
I'm new in this forum.
And I'm trying to fix and Old Onkyo a809 Stereo Amplifier.
Well everyhing started because, when I was listening some music in the amp, right chanel sometimes started to make some scratchy sound and sound got distorted.
I was reading in some pages that this is caused because some electrotic capacitors in the power suply leaks some AC voltage, this amplifier was made I think in 1992, so capacitors have almost 20 years, Original capacitors are 18000uf - 63 volts, I didn't find them, so I replaced them with some different value, 22000uf - 63 volts,
New capacitors are half of the size than old capacitors
It took me 2 hours to replaced them because of the cables, after that I turned it on, and it sound for a while, new capacitors got burned, and blown.
Do yo think any other components got damaged?, I hope only capacitors be the only problem.
Why does it happen?, is it because they're differente value, or because they're small size?
Any ideas would be appreciated.
I hope I could restore this old amplifier, it has a lot of power.
