Thank You.
What have those Sankens of different from T0-247 regarding PCB? I thought you just needed to set them more apart becase they are broader. Am I wrong?
ATAUDIO No , you have right , of course because of size MT 200 , but terminal are identical with TO-247 . 🙂
viki_v2 it was my plesaure to help you and guy from DiyAudio forum .🙂

Now that the amp is ready I want to make some measurements, I don't know what measurements to take and what sort of hardware is needed for this.
With DMM only measurements of DC offset and bias is posible, do you have a scope?
In thread http://www.diyaudio.com/forums/analog-line-level/167363-mic-line-eq-preamps-26.html post #259 you can find preamp pcb design by 'QQ12e5k1'
SR200 Completed.....
Hello Sir Apex,
I have just completed my first channel of your SR200 design. I must admit, this is one good amplifier.....the sound is one of the best that I have heard in a long time. Bass is good, mids and high very clear. I connected input straight from CD player, no preamp, and I must say, this is one excellent amp. Here is some pictures of my first channel. Planning to build second channel today. 😀😀😀
Thank you Alexx mm for a wonderful PCB design. It is easy to build and work first time. Thank you very much. 😀😀😀 Just one small request, as you can see from my pictures I only have two power transistors populated. I cannot fit a third one in this PCB. Space is a bit to small for 3 outputs. Can you modify this PCB by increasing the spacing between the power transistors, as I would like to populate 3 power transistors. 😉😉😉
One Question Sir Apex. What is the maximum voltage for 2 power transistors in output?
Once again, thank you very much Apex and Alex mm for a wonderful design.😀😀😀

Hello,
Nice to see another SR200 Completed, We share same feelings about the sound.
Regarding pcb I too faced the same problem, So I increased the print size by 3.5 mm on all the four sides. this will allow three transistors to be mounted easily.
Happy diy.
RE Print Size
Hello Viki_V2
How did you do this? If you increase the print size, thus the other components still fit? what about the IC pins, are they still ok?
