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.

Just wanted to say that it's great to see you participating on the forums. I've been a fan of yours for a while, and my dream setup is using your amps. Because of your whole philosophy towards audio basically, and I'm part Polish too (I'm assuming you are, but with a Ski at the end. I'm pretty sure you are. Lol). I love that you design to be stable, and avoid failure. I don't have time to go through all this right now, but I almost died at the first question. As far as I know. You make tube amps that are easy to use, and are for the long term. That sounds good to me. The fact that they also sound good enough to keep Stereophile A ratings for years means a lot to me too. 

I wish I lived in California. I would most definitely check out your school. I honestly think it just needs to be pushed more. I'm willing to bet that Burning Amp alone will help. I know you can't just spend, spend, spend, but maybe some directed advertising on Facebook towards people that are very interested in learning electronics would help. You might pick up done young people struggling to afford College? Something different should be tried, either way. Because if the word doesn't get out. No one will ever know. It's that simple. I only found out about the school, because I was on your site, for instance. I think it's a great thing you're offering, either way, and bless you for doing so sir.

Can't wait till I have more time to read what you've wrote about biasing in particular, as it's fresh on my mind. What with buying my 3rd tube amp this past week, and still not knowing how to do it, and even worse, not knowing the theory behind it all. So I'll thank you ahead of time for that, and wish you and your family a Happy Thanksgiving.

Thank you

Sorry. I don't know how to use quotes and all that on this forum. No offense to anyone, but it's beyond outdated, and I've been into computers since the mid 90's.

Anyway. Thank you @ramtubes. I agree that Facebook, and Z, both suck. But you can still effectively use their ads I feel. That being said. Google Ad-sense is a great alternative.

And thank you 10 times over about the OP-amps! I've been told a million times, that it's not OP-amps, it's how they're implemented. When I say I won't buy anything with them. BS! I've got very sensitive ears. It's definitely the OP-amps. They suck arse, period! And I'll have nothing to do with them.

Hope your Thanksgiving was half as good as mine was. God bless!
