Re: Help needed with no trace no beamfinder on 465 (not b)

Thank you Albert. I put the scope in dc coupling and centered it. Needed to adjust the scope to .5V/div in order to keep the same gain for comparison.

Here are the waveforms:

/g/TekScopes/photo/49286/9?p=Name,,,20,1,0,0

Collector is a hair more than emitter, base is a little more than twice the dc bias, as you say about 0.65V.

Is that the correct way?
