Tektronix 7905 Oscilloscope
I bought a used non-working 7905. Have almost everything fixed except:
When increasing the trace brightness to an acceptable level there is a halo present. It is not a uniform halo, but is displaced slightly up and to the right of the trace, probably 20% brightness at normal brightness of main trace. The focus and astigmatism controls work properly. Your help will be appreciated, Thanks, Emil |
