DEC TSZ07 ..relabeled Cipher 9 Track tape?

Hi, I know that the DEC TSZ07 9 Track drive is made by Cipher. Does someone here know if there is a near equivalent Cipher Model? The Cause of my Question ist, that I think I have a ugly fault in the PSU, when the Drive is in standby, some parts of the circuit are overheating. Look here for pictures: http://www.tiffe.de/Robotron/TSZ07/ I've repaired the PCB but the parts are still getting hot in standby, because standby no fan is running.. Since the Technical Manual of the TSZ07 contains no schematics, I've looking for the equivalent Cipher model to find schematics of that PSU... Kind Regards, Holm -- Technik Service u.
