Re: 465M horizontal amplifier x10 magnifier problem

Hi Manfred! I`ve just finished a 475, which is similar. It had a similar
problem which was completely cured by replacing a transistor in the sweep
circuit. There are 3 sweep circuits, so you can swap transistors arround.
Good

Manfred,
This sounds like a Mixed Sweep mode, which I'm pretty sure the 475
has.Does the sweep "kink" move when you turn the Delay Time Vernier
??"Mixed Sweep" runs at the "delaying"/main sweep speed until the trace
gets to the point selected by the DTM knob (Delay Time Multiplier)Then, it
shifts to the "Delayed (faster) sweep for better resolution.If the "kink"
moves horizontally with the DTM dial, then it is working correctly.
