15 min repair: llämp. Power transistors were fine, so were the diodes and the driver transistor. In the end it was a broken primary on the output transformer, luckily right at the connection.
Three out of three dead octek boards with Headland chipset. Although I think on this it's a mechanical issue. It broke after handling it to try the 287.
It hangs after step 04
