Good advice from Chuck Harris about care in removing wires from the CRT pins. On a related note I once was asked to repair a 535 scope that had damaged resistors in the VA because the wires had slipped off the CRT pins and come in contact with the chassis. This destroyed the non inductive resistors in the plate loads of the output tubes. As part of the repair I put a a dab of conductive glue on the connection to make sure it couldn't happen again.
