Forte Model 3 advice needed


I'm about to checkout a Model 3 locally for sale. Just a few quick questions. What size fuses should she have? What would be the common falures for a this amp? I'm quessing like mabee cooked bias pots or dried up caps. About what temp should the sinks run at idle? Are the bipolar outputs still available in the proper matched beta ranges? It's a good looking beast and I've allways lusted after a Pass design. Is there any reason not to jump on her?

Thanks in advance.
