I have a set of sea wolf pcbs... they were working when I had the cab but I sold it 3 years ago
I dont think i have a way of testing these pcbs now as I dont own any black and whites anymore so I dont know if i can test them (well perhaps i can do power and sound and inputs via my jamma rig)
Im thinking $75 shipped (Ill do the above test but it'll be video blind) and also your also paying for airmail as Im in the UK... But I cant doa refund beyond that - once shipped theyre shipped, so I can see from your pov its a gamble but then I cant do any more im afraid
