Default David Eden WT800 amp, 2010 date, blows mains fuses

Sometimes after 1.5 hours originally , now sometimes soon after switch on ,
sometimes a bit later.
Amp plate says 5A(T) for 240V use. Inside the IEC, is one non-blown 2A(T) in
the active position, ah! the simplest of repair jobs, BUT
No reported noises like magnetisation buzz or speaker noises , no smoke or
smells. Owner uses the same cab and speaker wire with another amp ok.
No blown fuses retained by the owner but reported to be blackened. 2A fuses
passing 3A or so and then failing when asked to pass 4A say, but they will
have fuse-wire breaks , not vaporisation and blackening.
Tx torroid 0.8R or so per primary , measured cold, seems reasonable for
135mm diameter, 65mm high Tx. Not in a position to check the main caps yet ,
but no bulges.
Any Eden usual suspects? PbF and RoHS stickers a-plenty
