This is the one saved from the skip, when power applied it worked , sort of , then it became intermittent, the fault was traced to the IF module ,having removed it I could see it had been worked on before , one transistor replaced, I disconnected the screen from the other two although no leak was found , the intermittent was dry joint's on the wire connectors on the rf side of the module , a good tip is to re solder all these connections before re fitting the module , It cleaned up nicely . another one for the collection , Mick.
