2. amps-preamps
  3. 140029-80294

Does anyone care to ask an amplifier designer a technical question? My door is open.

I closed the cable and fuse thread because the trolls were making a mess of things. I hope they dont find me here.

I design Tube and Solid State power amps and preamps for Music Reference. I have a degree in Electrical Engineering, have trained my ears keenly to hear frequency response differences, distortion and pretty good at guessing SPL. Ive spent 40 years doing that as a tech, store owner, and designer.
.
Perhaps someone would like to ask a question about how one designs a successfull amplifier? What determines damping factor and what damping factor does besides damping the woofer. There is an entirely different, I feel better way to look at damping and call it Regulation , which is 1/damping.

I like to tell true stories of my experience with others in this industry.

I have started a school which you can visit at http://berkeleyhifischool.com/ There you can see some of my presentations.

On YouTube go to the Music Reference channel to see how to design and build your own tube linestage. The series has over 200,000 views. You have to hit the video tab to see all.

I am not here to advertise for MR. Soon I will be making and posting more videos on YouTube. I don’t make any money off the videos, I just want to share knowledge and I hope others will share knowledge. Asking a good question is actually a display of your knowledge because you know enough to formulate a decent question.

Starting in January I plan to make these videos and post them on the HiFi school site and hosted on a new YouTube channel belonging to the school.

I've been here since its inception.
Does that give you the right to be a self proclaimed forum cop.

This thread was put up as a promotional device.
That's the pot calling the kettle black

I notice on this account that Georgehifi isn't being taken to task;
Wow, you've really got something up you this morning, must be the bagging Class-D's getting on the other thread, and you keep saying (promoting) your is coming soon and it will fix all the problems with Class-D.

Of course not- neither am I attempting to enforce any rules.

Oh- can you point me to a thread I've created on this site? Meanwhile, irony is still a thing, huh?

?? Did I promote such a thing on that thread? I did provide info but IIRC no information whatsoever about what we're up to.

I greatly value Ralph Karsten’s forthright yet tactful comments. I learn something with out being belittled.  He dignifies the other person by doing that. Thank you Ralph, Almarg and others like that.

Not on that specific thread, but you have numerous times, what was it that was said???oh yes!!!
"LET HIM AMONG US, WHO IS WITHOUT SIN, CAST THE FIRST STONE"
Think that was it, I remember reading it somewhere, "How to survive in the Australian outback" or something,  correct me if I'm wrong.

Really!!! by saying this about Roger, who is helping others with their questions with this thread.

"But here’s the kicker: This thread was put up as a promotional device. You can tell because the manufacturer is talking about his products, often more than once in many of his posts."

I think you have that totally "arse about face", marqmike

Cheers George
