Hi all, repairing this unit where the speaker protection relay has been melted by two 5 watt resistors next to it burning up. Easy enough repair as far as that goes, along with two shorted output devices. My issue is, the copper tracks under the board have been burnt up, and I cannot locate a schematic for it. If anyone would have a copy of at least the copper side of the board, that would be a great help. Cheers. Geoff
