Heavy Duty 150W Amp

Thanks a lot, and please, put your face together, let us see you too.
If not to pretty, do not worry, i am not, but i am surrounded of woman, and the secret is, never let them know how much you love her!...beeing cold, you will keep your heart warm.... trick, they do not like nothing easy... in your country can be different, but i do not believe, because my first wife was Danish, Wendel was the name.

So, thank you, and send me your white face in direct Mail.... i will send you my yellow face too.

I want to assemble, this way, if possible, send me hi resolution picture, the maximum your machine can make, use "macro" regulation if possible, i want to read values too.
Limit is 10 Megabytes because my mail box.

Thank you choco, wonderfull, das ist ein klein wunder!

Another hint for simulation:

The used OP amp model must reflect its output in the current which it draws from the supply.... Some PSICE models may only show the behaviour from the inputs towards the outputs, such simplified models will not work for simualtion of this circuit.

@Carlos
OK, I will send some more detailed images by mail.
I would propose to go for slightly larger heat sinks.
My consruction runs close to 60°C, the small heat sink of the driver is even hotter at about 70°C.... pretty hot design..

The resistors of the output stage are non inductive types.
Some metal oxide, if I remember right.
The 47uF must have short electrical connections to the collectors and together, so that they provide a very low high frequency impedance from collectors of BDW83D to collectors of BDW84D.

I received the hi resolution pictures i asked you.

And my daugther said you beautifull, and they like the automobile you used!.... my wife also ask me to crop in your face. grummpf!!!

This way, my dear friend, if you arrive in Brazil with your damn charm, please, tell me.... i will charge my double barreled Shot gun to avoid competition.

Hey, they order me to bring you here if arrive in Brazil.... grrrrrrrrrrr! (remember a dog?), no problem!, i have more wifes...no problem, i am not Jellows.

Very nice, your amplifier, the problem is that have not space enought to be more pretty....if 5 meters lenght will have enough room to be more beautifull.... really, like it.... sorry to say..... some amplifiers, having some Choco characteristics, will appear here, down in South America.... if you do not mind..... i will put my name together your, Keckschwimmer amplifier.... sorry....we are not very much worry about rigths....but, as i like you, i will respect you if you said clear NO!... If not, i will change a little, because i saw where to change, and i will do it as Keckschwimmermann.

Thanks a lot.... about my girls....hummmmmm.......grrrrrrrrr!

Simulates very well in multisim.

Hi Carlos, funny guy !!!

It's fine for me, if you start to distribute similar amps or even direct copies...
Well, to be frankly. It would turn me proud to see a revival of that circuitry.

Cheers
Markus

P.S.
Ladies in Brazil like my face?
Could you please tell this to the ladies in Munich...?
