A manual hard to find. It was very helpful to restore my device.
;
I am very grateful for this manual. Without it could not repair my receiver.
;
excellent work as always you do cheap, fast net and clean. you do an incredible service......thanks!
;
Great Job even clear than the one before!!!! god organization- I'm always very satisfied
;
I'm very happy that you all are performing an incredible good job. Furthermore what you did is very useful for all people as me that have electronics as an hobby.Thank you!!!!!

U : B+ Line. V : B� Line. H : adjustment for repair. Voltages and waveforms are dc with respect to ground under no-signal (detuned) conditions. no mark : POWER ON � 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 : TUNER
