Default Re: Quad II problem - Rectifier blowing (GZ32)

Providing that you did actually remove the wires from the X, Y & Z terminals before measuring resistance to chassis (thereby eliminating any path to chassis from elsewhere in the wiring) there must be an internal short inside the output transformer. If so, that is most likely the cause of destruction of your rectifier valve. Getting the transformer rewound or replaced is your only option. Jerry
