Hi again,
So, I tried the cord between the send and the return jacks and it worked! Thanks for the tip!
While this is certainly a good workaround, how would suggest to fix this? This may.simply be related with some dirt in the connector. So, replacing it may be a bit of an overkill. Any suggestions on how to clean it up?
Since I have the amp opened and the PCB's are exposed, would you suggest any procedure to avoid other issues, like cleaning it up?
Thanks and regards,
Bruno
