Very pleased with manual except that a few more details in the drawings might make the job (not yet done, tut-tut) easier. Should be adequate though. Actually I didn't have to pay for this anyway as I was given credit for another item that wasn't quite complete. Good service, then.
A great manual; it contained all the information I required and allowed me to restore the receiver to full working condition!
