Yes absolutely agreed.It seems that lots of peopel encounter a humming noise in PSW models after some years' playing, I am a electronic engineer and I had inspected the PSW2000 sub, and found that it C52 would be dry out by heat
which generated from the beside resistor.So just to replace some capacitors is not fully solve the problem,
maybe some months later it would be humming again.
The root cause is to solve the heat problem, besides replacing C52,also remove the resistor and fix it onto
metal, it would he great helpful and I think the issue should not be happened again...
Hope aboved information would be some helpful to the people who repair the units.
This is why I produced the guides and modifications on my web-site.
