Hello Mr. Henry_hz

last week i bought Pass A30 PCB and resistors from you on taobao.

about silver mica caps you give me 100pf instead of 10pf, others are correct 1000pf silver mica.

can i use it 100pf ? or should i buy another 10pf silver mica?

1 more thing about R1 and R8 (100k* resistors) do i have to installed it on PCB? if im not wrong they are used for adjust bias current and DC offset..

i have DC offset about 10V at output ,
when i installed R1 and R8 with 100K resistor3 IRF240 are hot and others 3 seems like not working since its not hot at all

then i tried to remove R1 and R8 and both side seems working all 6 IRF240 become hot and i still have DC offset about 10V

btw i bought all Fet  from Hifi-zone which is matched to 0.2%

from what i read A30 seems to have hight DC offset around 3V when you turn on for the first time and become lower as it becomes hotter, is this true and normal?

if anyone know any guide or tutorial for debugging A30 please let me know.
thanks
