Those resistors do not form a load to the chip. They are emitter resistors of the output buffer. The load in my tests is output to ground.

I just moved to a new house. The last two weeks was packing and unpacking, and converting a store room to a lab. Hopefully, I can resume my projects in couple days.
Panson, can we help with your move? The entire DIYAudio board is awaiting your help!
I'm excited about your LME49810 kit and the Thermal Trak power stage.
You bet the neighbours are going to hear that, and come over with their favorite CD's.

Thank you very much! Please help me to solve the heat problem of my lab room. It is basically a glass room extension of the house, a good place for Sauna
. I will put solar reflective film over it to block the sun light. Hope this will work.

Yes, I have air conditioner in that room. However, it is overwhelmed by the heat. I put solar film to block the sun light yesterday. Lets see how good it is in sunny days.

What about deodorant?
I have been to HK on biz -- it's not as bad as Kampuchea in the summer!
New version of driver boards just arrived! I will focus on 49811. Pls see details in http://www.diyaudio.com/forums/showthread.php?postid=1814571#post1814571
hi!
i am a new member on this forum. I am from Slovakia 🙂 . I take registartion on this forum because I need a library on eagle LM IC . 🙂 I download it and use,but in real is on **** because pads is small a little close together. I must edit it,but i am lazy 🙂
I try made a my first amlifier, therefore my design ,not first build. Is simple. I use a Tesla darlington transistor KD366/367. I calculate with output power 30-40W and supply voltage cca +- 25-30V.I have not a SOAr ,only suppose this parameters, see in real measurement 😉
this is my PCB http://ujoelektron.ic.cz/upload/MPZ30.png , but need a redesing ,because it have a very bad place a part. soon take a photo how does it in real 🙂
P.S. sorry for my english, could be better ,because i graduate on secondary/high school technical and i graduate on english language

Due all respect, but this is very narrow minded. With this attitude you will you will never discover something new, and maybe better.
Sound Quality is something very subjective and always open for debate. But judge something by forehand because it is an IC is very odd.
I think it is very very hard to design a VAS that can outperform any of those driver IC's. Not even to mention component tolerances and matching.
IC's today aren't like the IC's yesterday anymore 😉
With kind regards,
