Hi everyone
Here we are having the may 24 weekend. Hope all are enjoying it.
I hope this is the correct thread considering it feels with wiring.
I am building a modulus amp kit and they have a shared ground for a 33uf cap circled in red. Still learning so I'd like to ask. At the moment the amp has a very low frequency hum with the master volume pot at zero and it goes away as you turn it to max. So I tried everything to ground the way it describes in TUT. I'm sure that's not the issue. But.. after all possible ways I pulled out the preamp tubes to see if it goes away. Still there. The low frequency hum (I'm guessing 60HZ) is definitely from the power section somewhere.
Also I tried reorienting the output transformer and moving it away but still there.
Now the only culprit I could think ofnow is this shared 33uf capacitor. Is it still a good idea and good practice to just get two 33uf caps and seperate their respective grounding? Or in this case would it not matter so much in terms of reducing noise.
