Greetings,
?
I just recently got my 7CT1N working with my 7B70 and a 7A26 in my 7603. Yesterday I went to try it out with a new adapter and found that no trace is being generated. The dot can be adjusted to the lower left but no traces occur as the collector/drain control is increased. The dot moves to the right when the pnp button is pushed but does not move to the upper corner. The dot responds to the verticle position knob on the 7A26, the horizontal position knob and the variable knobs on the 7B70 but not the position knob on the 7CT1N. I cleaned the switches last night but no change. The adapter is not present when these test are made.

Where is a good place to start? my 7K extender is not very good. The scope functions correctly in normal operation with the 7B70 as a time base.

Thanks,

Ike is coming tomorrow.
