i recently repaired this amp with new fets and a few broken grounding traces to fets and everything seem to check out after. i did one last startup before stress testing it a bit and i saw the amps spiked and big sound from my test speaker, after a bit of testing i found out that after removing the probe something causes it to wack out, spiking current and a ton of voltage on speaker and protect light swithes fast along with a buzzing noise. theres no dc across the speaker terminals and so on so iam thinking that the GND for rca might be wrong and grounding throught the ocilloscope. im running a pico scope and rca directly from pc for test sound and a RND 340-kwr-103 as power supply and have never had this behavior before.
ive checked the gnd trace from input jack but cant figure out where it ends.
any input anyone?
