I probably did not read it well enough and you ment something different. Must be a smaller X amp?

Okay thanks.aha, then it is 60mV
not enough coffee today, I had wrong SM opened
But with almost an hour warm up and bias around 60 mV's for both sides, rails at 65 Volts and AC at 240 Volts, the AC uptake is 415 Watts and not 600 Watts.
411 Watts to be exact. The German engineer measured 405 Watts at idling...
Are you sure about that 60mV biasvoltage? Is it indeed in the Service Manual of the X600.5?

Dunno, for sure
I mean - I know how I would solve any possible dilemma, but finding exact data in case that figure in SM is under doubt of being unintentionally wrong figure - that can be tricky without contacting manufacturer
in short - now you really can have exact reply only from PL, but as it seems , you shut that door pretty tight
I told you - all you had to ask in first place, it needed to go to PL first
in today's PMPO watts world, they're one of rare Lighthouses, whatever someone could think

Or just increase the bias till the heatsinks are 50 Degrees Celcius so you cab barely touch them? I've seen that value as optimal a few times in documents from NP/PL
So I've stepped on some toes and I'm doomed... Well I know for sure that NP or Wayne or these guys at PL aren't that way so I ask them.
Again, did you get that figure out of a Pass Labs Service Manual from the X600.5 or not. I have to be clear on that before I resort to PL again.aha, then it is 60mV

that
btw. you can still edit your first post, just to be fair to PL - clearly asking for solution for your pair of amps
and leave note about edit, just to have things understandable
Thank you very much for that part of the X600.5 SM, that is 100% clear.
I'm glad at that 60mV the amplifier consumes 411 Watts at idling instead of 600 Watts.
Maybe at 240 Volts AC it needs less power from the grid. I'm sure there's an explanation for this.
Strange that the German engineer got a reading of 405 Watts at idling, that's not far off....
I'm really confused now so when PL Service replies I'll let you know.

Yes. Amplifier is actually consuming 540 -550 W from the mains, which is spot on according to the manual attached by ZM. There is specified 2.3A at 240V. Power measured by meter, due reactive nature of transformer, is around 400 W and that is what you pay to the power distribution company. 😀
I pressume you mean that the power distribution charges me for the higher VA value? Okay clear then all is okay and the amp performs as specified in the 'Adjusting the amplifier' page Zen Mod kindly supplied to me.

Done that.
Done that.
No, they charge you only for 400W as their metering devices also doesn't measure reactive currents.
That makes for very musical heating appliance with 134% efficiency. Who dares to say that A class is inefficient?
Great! But I won't tell them or any environment type that I these babies sucking up 1100 VA an hour...
They do heat up my listening/working room a bit so I can be prudent on the natural gaz...
leave a note that you edited original post, so it's clear why later carnage ......
