Now I listen with the Charcroft Z-Foil Resistors 2K2 0.4 w.
Upcoming weekend I will tell you all how it sounds in my set.
I got the idea that certain tweeks, not appreciated in this topic.
I think it people seen this tweek as snake oil because I also get little to no response my entry in connection with the 1uF in signal path.
Regards,
Rudy

Not sure about the others , but i never intended to use input cap ...
Please post what you do , so far we are happy to know the MK3 is indestructible..😀
On a serious note , post what you find, there is always something to learn/ do , if you start to play with the NFB values , i would be interested in hearing your discovery ...
Mr. Rudy Sir, Please do not take offence to what I posted I enjoy reading your changes to your amps. However lets carry your mods a little further,,by putting in a seperate front end supply and then driving the output stages,,Then you,ll really hear a difference.
Again forgive me for offending you. Kisses Evette

Hey Mr. Wayne I,m sure your working very hard on your amps and I,m sure you,ll have many wonderfull hours tinkering with them is there anything I can help you With😀😱
Hi Evette,
It is no problem, I thought there was no interest in modifications that I do.
Tell something more about the modification where you're talking about, maybe to design a new board?

Rudy
Yes, My list is long ... I will send by courier .... 😀
Not so Rudy, maybe people don't respond at the moment .. same as you !!! 🙂
You're right Astankov, I was pointing to the wrong resistor. The picture below is corrected.
Well, to emulate the gain of a 200W RMS /8 Ohm consumer power-amp, the values should be around 47K for R11 and 1.8K or 1.6K for R09, which would give a gain of around 27-30.
So an input of 1.4v RMS would give about 200W RMS into 8 ohm.
Please always correct me when I'm wrong 😉 hahaha.

Canonnica now is correct. You can use this formula for easier calculation:
Gain= (R11/R9)+1
Meanman what software do you use to produce this board? It is really beautiful and I want to give myself a try with this software.
Have a nice day everyone!

If we create a better amplifier this way, why than a new board with 4 trannies?
Patrick is it not better to create a new structure like Evette defines?
I'm going to build a new Dx Blame MKIII-Hx only if I definitely know that it gives an improvement.

Looking good meanman , since only 8 outputs can you add a bit more spacing between outputs for better temp spread .....
Rudi,
Regarding the quote take a look at my example then you'll notice it's done.
The reason for using 4 pair trannies is to reduce board size a request from Vigier.
