kevin gilmore Posted Tuesday at 09:30 PM Author Report Posted Tuesday at 09:30 PM (edited) q12 is the current limit. so if the amp board shorts, at least the power supply will not explode. what do you want me to replace the pzta part with? remember 20+ma Edited Tuesday at 09:38 PM by kevin gilmore Quote
simmconn Posted Tuesday at 10:53 PM Report Posted Tuesday at 10:53 PM I was just pointing out, as how Q12 is connected today, it’s not doing what it is supposed to do. The output should be connected to gate instead. I remember last time you recommended TTC004B as a replacement for the PZTA42 (different package). We just need something with a flat hfe-Ic curve to, say >100ma at VCE=10V. Quote
JoaMat Posted yesterday at 07:06 AM Report Posted yesterday at 07:06 AM Seems simmconn reads shematics. Regarding Q12, schematics and gerbers don't match, I think. 1 Quote
