btw what do you think the 100ohm resistor and the 100nF cap offer in parallel to each diode in PS1-PS?
i did run a PSPICE simu but didnt notice the advantage.

thank you very much for this thread.
Have had these thoughts for a while and just yesterday 2 of the mur802 rectifiers died on me. I have already ordered 4-5 rectifier bridge parts and i ll hardwire...

Sorry for not answering mr audiophool. i finally removed everything not required and i discovered many problems were caused by low quality switches connectors ect.

As for the secondaries i have...

the last two days i have been trying to get past the vpp vnn test.

Actually the mains 3A fuse blows whenever i have the PSU-PS1 connected on the transformer.
Is it normal for the Psu-ps1 to draw...

Thank you and you are absolutely right. The suplied led was smaller than usual and i didnt look carefully.

You see i realized this yesterday and since then i moved forward a bit. I did the 10v...

Thanks for the response.
I didnt see the 10ma step down. i checked the soldering as well as verified the whole muting-protection part of the board. its all as the schem says.

Is it possible that...

The main idea is to fit the power suplies transformer unit in a seperate box next to the actual amplifier.
The size of the toroid transformer was a good enough reason (16cm in diameter and 10cm...

When testing 5v standalone I connect the 5v to the truepath board and get the voltage reading as planned. When i measure current i get 12.5 ma without the short between HMUTE and 5V. Then i short pin...

I just tried my first step. Turn on the power suply by it self and then maybe test it with a load.
when i turn it on and measure voltage i get the readings i should but when i turn it off sumething...

1. ok so if i connect it on the softstart board on the pins that i would connect the 2x40v transformer both 40v and 12v will start soft but at the same time. If not please enlighten me.

2. I have...

I have completed assembling 2 true paths and now its time for tests.
I am a complete newbie concerning amplifiers although i have plenty of experience on other types of electronics.
So here are...
