Thanks Peter for responding.
I'm talking about the (blue faceplate) EML 100, not the 101, it has different waves from the 101. I've yet to see a full set of schematics. OSC 2 and OSC 3 on the 100 are definitely not identical as they are on the 101 schematics. Though I've not attempted yet to compare their differences from the 101.
I was scoping the waveforms via the OSC 3 out jack up top and the filter mixer out jack up top.
Then again contemplating further. OSC2 which is working shows a cosine to a half rectified (co)sine going to a square on the front panel and I'm getting that when looking at the actual wave. So OSC3 seems to be intended as having a triangle instead of the cosine looking at the front panel. So that does sort of seem like the clipped on the bottom only triangle I get in real life might be out of calibration and spoiling the 12 o'clock mix of waves.
The power supply was doing +15.5v -15.5v with original caps. Since I was replacing the electrolytics I did the power supply and the voltage remained the same.
I did not see any Tantalum caps in the 100 (or the 101). Has anyone spotted any?
Though still curious on the original question. OSC 3 on a 100 (not a 101), are the actual waveshapes (on a believed to be fully working unit) similar to what is drawn on the panel?

> I’m not so sure that graphic on the front panel for sawtooth is correct.That's what I'm trying to find out before I go back inside. The factory graphic (looks like a half rectified sine) has nothing resembling a saw at 12 o'clock (what Peter mentions) but then again neither does it look like my wave at 12 o'clock.
