Without your experience - I would not be able,Nikosokey 🙂
Now I want to use separate power and VAS, looking for a schema...
Thank you!
Rarely, I listen to audio.
If I have to answer your questions, I will not have the time to do either.
No SMPS, only toroidal transformer, in first picture ,and 500VA R-CORE in the second picture .
Regards,Alex
You, can read from picture, from where ..... They are, special manufactured ,for audio, and perform very well ,without noise and small magnetic loss .🙂

I can confirm Alex words. I use one of my five collection in NBip build. I will use rest of group in several slewmaster build.

Thanks Alex.
So you only have about +/- 50V on your ampboards?
No problem then with pretty high bias.
+/- 80 V on the other hand would cause a VERY hot amplifier, don´t you agree?
No, bias current is bias current.
If you increase the voltage you turn down the bias back to your chosen current.
The Perreaux I am repairing has ±115V and is set to only 170mA total per channel = 34mA per pair as it has 10 devices per channel. The heatsinks are about room temp.

I know bias current is bias current , but power consumption is very different with +/- 50V @ 150mA bias and +/- 80V @ 150 mA bias. That was my point.
Yes, sorry, my mistake, my brain was off-line at that moment due to a flu or something. After a good sleep I could then again remember and comprehend that the Wattage to be dissipated is derived from the voltage drop across the device x the current through it.
At that impaired moment of typing I was thinking (or not!) that only the current determines the heat, but, of course, the resistive element de-energises the elections higher potential into lower potential, energising the device into becoming warmer and the higher the potential, the greater the de-energising.
Nagys removed them.
It's a standard problem when Members refuse to attach and instead use a remote server that can go off line.
