Title: Kenwood CS-5130 scope trace intesity issue
Post by: Autronic on February 19, 2018, 11:42:28 pm

Hi,

Recently purchased a Kenwood CS-5130 sope that has a trace intensity issue. At cold power-up the trace intensity is very high. As the unit warms up the trace intensity will decrease, and the intensity knob needs to be turned to maintain a visible trace. Warm trace intesity is OK, but there is very little rotation left on the knob to increase the intensity.

Otherwise the scope functions fine, and has some excellent features.

A service manual, or any other assistance resolving this issue would be appreciated.

Regards, Chris
