Re: 468 sweep offset issue

I didn't get to do much today, but I checked the waveforms at the disconnect amplifiers for A and B.

The waveforms sync up, but the A disconnect amplifier (at emitter) is .5V high ( -2V instead of -2.5V) and the B disconnect amp ( at emitter) is .3V high ( at -2.6V instead of -3V).

I'll do more tomorrow - hopefullly I will have the time to check the entire sweep logic section and find the out of tolerance resistor(s). It appears that is what I should be looking for... (am I correct?)
