I have three skipper 300 and one 300a amp you were the only one that tried to help. I thought I could do the fixing the broken amp thing, um no if i shipped all four amps to you would you fix one and you could have the other three ? I have a lot of the parts two are 6lf6 amps and two are 8950 Amp. I only tried to fix one it's getting worse not better I can pay for postage. I just want one working sweep amp.
