I am using a NAD 1000 as preamp, or a DIY tubepre( DIY ECC802S (12AU7 / ECC82) Vacuum Tube SRPP Preamplifier). I also have a DIY el34 se, and when I use the tubeamp, there is no hum out of the speakers...I use different cables, no AC cables are near any signalcables. But with the Cambridge the hum is still there.
I'm not to sure either? I've had no problems with anything I've bought from there.
As to your problem, I'm afraid it has gone beyond my limited knowledge.

Richer Sounds is a retail chain of shops selling cut price equipment. They are also sole distributors for Cambridge Audio. As to the meaning behind the comment "Looks like RICHER SOUNDS strikes again", I'm afraid I haven't a clue. As I said, I've not had a problem with anything I have bought from there and there service has always been exemplary.
Think I am going to take a look at the capacitors and curcuitboard, perhaps I find some defect components.
I working on a Quad 303S now, changing the capacitors.

Careful Puffin.
Bridging results in the amplifier seeing a load rated at half the actual speaker you use.
If you have a pair of 60W into 8ohms power amplifiers and you bridge them you end up with an amplifier rated at 120W into 16ohms.
Turning that around. If you want 200W into 8ohms from a bridged pair of power amplifiers then each Power Amplifier must be rated for 100W into 4ohms.
Jempie is claiming to operate bridged into 4ohms meaning his amplifiers are each driving 2ohms reactive loads !
Is he being sensible?

Hi Andrew,
Is there a simple way to give the p500 more power
By changing the voltage or anything else
Thx

If each of the amplifiers inside the stereo casing are rated at X watts then the total for the two channels is X+X = 2X watts
That is fact. You cannot change it.
If you still think that bridging gives you extra power, then you are misguided.
Two channels of X watts when bridged gives 2X watts (into double the load impedance). The same rule applies.
The maximum from the stereo casing is still 2X watts.
Good point Andrew. I am normally virtually comatose after 8pm and had a job to find the EPE article let alone remember the rest of the post. When I first posted about this the doomongers were saying that the wavy bacofoil that passed for the heatsinks in these amps would fry the Sankens. Into 8 Ohms they are just nicely warm, but 2 Ohms?
