  1. Hi, I tried to build a twinsid from yodabe and I had problems with it. This is a link to the previous post: Now I have etched my own board and I am having problems with the Right channel. Left one is working fine. I have tested the right channel (connected with the j14 of the core module (pin 27 of the pic) with the testtone app and it works. It has passed all the tests with the interconnection_test_v2 except the pin8 of the sid chip, it's not giving me the right voltage. It should be 0V when I press the Key on midi controller but the voltage is changing between 0.3V-0.9V It should be 5V when I don't press a key but it stays the between 0.3V-0.9V The pin 8 is connected to j14 of the core module (pin 27 of the pic) and I have tested the solder joints, it is all fine. There is no shorts or anything. I did another test and connected the pin 8 of the right sid module with the pin 24 of the core module and it works. What could be the problem? I have attached my board. stereo sid SILK 01.pdf This guy seems to have the same problem but his worked for a while Thank you Kike
