New book on LTSpice Circuit Sim. by Richard Kuehnel.

[SoulFetish]

Just saw that he published a new book in September on simulating guitar amplifier circuits using LTspice.
Guitar Amplifier Electronics: Circuit Simulation
I have his book on designing output stages, and will probably get this book as well.

Anyone read familiar with this one yet?

Will buy, thanks for the tip!

I'm sure I will like it just as his other tube books.

Edit: Just ordered at amazon.com.

The Author has published a more theoretical book on using LTSPICE with tube a few years ago, hasn't he?
(I remember from the now defunct roehrenbude forum).

Richard sent me a copy (green cover) for review...he also sent me a copy of his newest (red cover) book: Fundamentals of Guitar Amplifier System Design

So what is your review?

Uh oh... He didn't say "Watts RMS", did he?

[Old Tele man]

Unfortunately, he does, especially in the green book; for example, on page 66 in Chapter 3: "At full power, the Champ creates about 5W RMS in a 3.2Ω secondary load."

And, there are a couple in the red book; one on page 16 in Chapter 1: "...so the amp is at full power, a very loud 60 watts RMS.", and another on page 163.

However, I believe what he was wanting to convey was that the power levels were created from sinusoidal test input signals and NOT from real guitar "music" inputs....ie: test vs. real-world inputs.

.. so. I guess it has to fall on us, Tele. Are we gonna' let it slide this time?

If CE recommends "watts RMS" on product marking, what are you going to do?

I decided to use "mean (or average) sine power" instead, here on the MEF to avoid further discussion. Definition being Pav = Vrms*Irms* PF, single frequeny, PF being the power factor (PF =1 for resistive load).
In Germany we use the term "Sinusleistung" (= sine power).
