Hi guys!
I bought an diy G9 dual tube preamp(For almost no money), it had no tubes and maybe some minor problems- after putting new tubes in it i found out that it has hum problems(I have tried with other tubes, no difference) .
Channel one sounds like this:

Channel Two:

Do you have any idea to what could be causing the problem?
Best regards
Johan
