Correct. The AP1 has a distortion residual output (called 'processed signal'). I plug this into one of the Rigol channels. After setting up the FFT I then turn off the signal display, so only the FFT is visible on the Rigol. It's a very simple setup, but I would argue that I have presented far more real-world performance information than other competitor books have, AFAIK.

Valve Rock Star
Merlin,
You present a persuasive argument.
You are a Valve Rock Star. The Figures in your book appear to be the product of hands on bench tests or graphs produced from by the applicable mathematics.
You present the theory, the math tools and the test results to drive home your lessons learned.
At this point I get the theory and the math. Sometimes the math is tweaked is to fit the test results. Empirically we create a constant to adjust the mathematical model to better fit the test results (curve fitting). Sometime the test results help me understand the theory better. To me it is about the process.
Thanks Merlin, keep on rocking.

Merlin Blencowe's Books and Publications Spotlight
Using the voucher code LULURC, which apparently still works even though it ought to be out of date.

Just discovered these books today as this Sunday I repaired my DIY SET Amp based on a Tubelab SSE Design, and... now I would need a Tubed Phono Pre-amp for my gf's vinyl setup.
Why, oh why can't we get the book in glorious colours just as the sample? The diagrams look so clean and beautiful in the sample.
And Merlin... that power supply book, man... we need another one. 😀

Lulu are offering 25% off today with the code UNIVERSE25, although I'm told LULURC still works too and gets free shipping too...

Florence Nightingale 's birthday. She's a bit more than 25 tho. The book is on my birthday list.
A really well written book and so readable too for a techy book. I'm loving mine and hope to build the phono preamp.
