Aion lab series l5
« on: January 13, 2019, 11:19:02 PM »
Hi. Just finished this project and i am having problems with r76. Before it, i have audio probe and tested the 4.40 ac volts as per calibration. Right after it, audio is almost lost and ac volts drops down to few millivolts. Any clues?

Power down and read the resistance across that resistor,, it maybe open and read a much higher that stated.

Thanks for the replies. R76 reads ok at 99.8k. It must be something with ic 11 or q1.

Solved. The 100p that was suppossed to be a multilayer was in fact an inductor. Bad supplier. Thanks a lot.
