Default Turbo current plots

Here is an LTSpice simulation of the F5 Turbo V1.2.

32 volt rails
1 amp total bias (.5 A per MOSFET)
4 ohm load
100 watts output

As you can see, the current thru the diodes "kicks in" smoothly.

Nice work
How do you add the extra y axis?
How long has this been a feature of LTSpice. I could not do this 2 years ago.

Ih,
I can't see a value for Rs (R7etc) for the output mosFETs.
Can you state Rs & the quiescent Vrs for your Ib=500mA/device?
Can you also add a cursor @ Vin=+0.5V (instantaneous value, not AC & not DC)?
Then read off the values of the various plots at that cursor?

I can't read that.
Any chance of a download of the asc file?

Are you confirming Rs = 0r5
Does that equate to Vrs = 250mVdc?

I can just about read that (but not quite) on this 19" monitor.
I wish I still had my 27" monitor, but I stole it to replace a broken down CRT television.

Andrew,

I can read it on my 13" Macbook Pro. (61 year old eye balls)
The full size image I can read after I zoom in 6 times or so.
Time for an eye exam.

Mr T apparently is a victim of his own small size image campaign.
