SR200

Good Day Kandimba,

Hope all is well... can I use your SR200 and SR250 layout's with Apex PA protect circuit?

I've attached pics of my protect build for my B500 amp that I'm busy building. This week I will make soft start and PSU PCB's.

Thanks in advance,

Regards,

Hi Macd! No !! For SR200 and SR250 you only can use the protection 7.

Hi Guys,
I will start PCB fabrication of SR200 V3 and PSU 10 from a professional PCB shop. PCB design done by Alex and Schematic from Apex Sir.

Starting a Group buy option for these PCBs to reduce overall cost.
Any one interested in SR200 v3 and PSU 10 pcb Group buy please let me know..

After getting adequate order numbers at least 20 boards.. Production order can be placed with the pcb shop.

PCBs will be of good quality having 2 mm thickness(for SR200) 1.6 mm for PSU , 90 um Copper, double layer.

Please raise interest to take this excellent amplifier project forward..

Regards,
Samrat
 
SR150

Hi folks, I have completed the SR150 build and I'm in the midst of testing it. So far the sound is very detailed, but I find the highs are a little too bright, almost harsh. I'm pretty new at this so any pointers are appreciated. :)
I've attached a pic and the files I used.

Thanks
R
