Original well scanned manual. Got the job done. Microwave problem found & corrected. For $5 and a new magnitron from ebay, it was a cheap and good the first shot fix. Electrical schematics allowed me to mage sure every thing else was ok before cutting and order for parts. Hard to live without.

WAVEFORM
Note on Schematic Diagram: � All capacitors are in µF unless otherwise noted. pF: µµF 50 WV or less are not indicated except for electrolytics and tantalums. � All resistors are in � and 1/4 W or less unless otherwise specified. � ¢ : internal component. � U : B+ Line. � H : adjustment for repair. � Power voltage is dc 3 V and fed with regulated dc power supply from battery terminal.

� Voltages are dc with respect to ground under no-signal conditions. � Voltages are taken with a VOM (Input impedance 10 M�). Voltage variations may be noted due to normal production tolerances. � Waveforms are taken with a oscilloscope. Voltage variations may be noted due to normal production tolerances. � Circled numbers refer to waveforms. � Signal path. F
