The 900 series 1960 cabs are most certainly not MDF. I never understood were this piece of misinformation came from. The back panels are particle board, so, maybe people assumed the the entire cabinet is? Anyway... I just got another JCM 900 1960A, and paid $300 for it. The tolex, and grille cloth, have seen better days, but, it sounds terrific. There's no way I'd pay what he's asking.
