Hello all ,I do not use this amp as often as i should (i live with a tv watcher)
but have a small system upstairs But a while ago switched on buzz sound
and magic smoke, thought prob the evox rifa across the switch had gone pop
to day my boy came, so i got him to lift it onto a coffee table, sowters very heavy ,,The input/ noise suppression cap is ok, but will replace with a plastic
one any way, The problem is the dc heater supply caps are short circuit IN5821 blown up ,heater wiring has got hot. so re cap required,, all under control
But the black gates they test sort ok, but probably best put in the bin !!!
what do peeps use these days ?
