In Reply to: Can anyone guess which amp-LT Spice posted by deafbykhorns on December 21, 2014 at 13:55:22:
The 845 op points shown do not make sense.
According to the 845 curves, 893.6 vpk never gets anywhere near a possible bias point of -89 v.
Using similar logic, drawing 79.4 mA under these parameters is impossible.
