AMP-70 Weird problems encountered in testing！
« on: March 30, 2023, 05:06:24 am »
Hi Guys
 I was recently testing a 100w power amp (AMP-70，https://www.diyaudio.com/community/threads/winfields-100w-dc-10mhz-1000v-us-amplifier.287023/) and according to JD's patch documentation, I built a flywire on the B side of the board
As described in the picture Added List of known issues

Now as soon as the power is turned on, Q27, Q27, Q28, Q33, Q34 will be shorted
I don't know if I need to disconnect or jumper the wires there in advance?
Also, is this J7 jumpered correctly?
Can anyone help me or give me some tips, thank you very much!
