Don, I see that you have a Loftech TS-1 Audio Test Set. Did you by any chance get a copy of their book: "Audio Measurements: Their Importance and How to Make Them" by Larry Blakely, John H. Roberts Phoenix Audio Laboratory (Loftech) 1982 87 pgs This book was a free companion piece for the...

Here is a list of books and articles. Many have active hyperlinks. Hopefully, you will find something of use. If you are interested in specific methods to measure rise time, slew rate, phase, etc using oscilloscopes, I have a list of books and articles for that as well. Books: Encyclopedia...

Here is a old article.... Click on the hyperlink below. Rise Time Measurements: What You See May Not Be What You've Really Got by Raymond E. Herzog Popular Electronics August 1972 pgs 60, 61

With regards to measuring rise time and/or slew rate: Typically you would generate a square wave with a signal generator/oscillator capable of sine, square and triangular wave-forms. These signal generators are also known as function generators. The square-wave signal would go into the input of...

It appears that the AP ATS-1-DD analog output spec for the square wave; rise/fall time is "typically 2.5 - 3.0us". NOTE: The rise time for Phase Linear 400, and 700/B series 1 amps were 1.6-1.7us and the 400, 700 series 2's were 4us. Ideally, you should have an accuracy ratio of 4-5 times...

There were (2) amps on ebay and the auction just ended. The first amp sold for $551 and the second one for $561. Did anyone on this forum buy any of the amps?

I called and left a brief message with Steve Mantz. I am awaiting his reply. In the meantime, I did a little more research and found some additional posts of his regarding Phase Linear using the name "MOER" on diyaaudio...

I would love to see the THD+N numbers at 20kHz both channels driven (at the same time) at rated output 360 watts per channel (53.66V) into 8 ohms. BW limited to 80kHz on your analyzer. Ed

Mark, Can you scan all the pages and save it as a PDF? Thanks! Ed

Some additional Steve Mantz ("MOER") postings. https://www.diyaudio.com/forums/solid-state/182404-recapping-phase-linear-400-a-2.html https://www.diyaudio.com/forums/solid-state/186493-phase-linear-oscillation-3.html...

It looks like the pc board has a discrete front end (no I.C.'s). NOTE: Phase Linear PL-36 p.c. boards used either LF-356 or LF-351 I.C.'s which were noisier than their earlier series one p.c. boards.

I contacted the seller. It turns out that I have heard about him in the past. His name is Steve Mantz and his business name is Zed Audio Corp. http://www.zedaudiocorp.com/pdf/history.pdf http://www.zedaudiocorp.com
