I have a Johnny Mnemonic that I have done a fair bit of work on to get it back to glory...weird thing is I cant turn it down lower than 8. I can turn it up all the way but turning down it stops at 8! Can anyone help?...there is a blown speaker...it works, it just crackles a bit but I would not think that would matter for this issue...just giving the facts...ultimately it doesnt matter but I want my Johnny to be perfect! Who doesn’t?
