Hello

I have a problem with my old tube Telequipment 43A oscilloscope, I use a
sine wave generator who work perfect and have only .01 % distortion, but
wen I feed my oscilloscope with any sine waves it's kind of oscillating
alway's at the right side of the sine wave in the screen of the scope. It
is doing that only with my scope, so it's not a problem with my sine wave
generator

Here a link of a photo of that, I was very close so it's bit out of focus
photo and it's hard to catch the sine with my camera.

What can by the problem ?

Thank

Try replacing an ECF80 in the X-drive circuitry, V107, V108 .
The one advantage of valve stuff - you do realise that it is about 40 years
old ?
