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 will be the first. I never owned an amp of yours. I have owned other tube amps by several other manufacturers. I gave up on them, and this has been through a pair of modified and tweek'd pair of Klipsch Lascala. Why did I give up on them ? Noise, microphoncs, pretty often biasing, warm up time ( I leave ss amps continuously because of the superior sq ). and " timing " in the bass ( muddy ). I go passive through a Dac. Should I try an amp of yours, and why ? I listen loudly to rock and jazz. Thank you... Enjoy ! MrD.
Hello Mr Ramtubes

I wish to get your opinion about SET and Push Pull tube amplifiers.

Sometimes double SET using two parallel SET also come up..

I like the mid range roundness of SET tube amplifier but they have limitation in power.

I have no particular question to ask at this time, Roger, but I want to take the opportunity to express my appreciation for your participation here. As with Ralph (Atmasphere) and a few other audio designers who participate here at least occasionally, I always follow your posts with interest, and I have learned from them. And I’ve learned from them even though I have BSEE and MSEE degrees myself, from excellent schools, as well as 33 years experience designing and managing design of sophisticated analog and digital circuits (not for audio), and nearly 40 years of experience as an audiophile.

Thank you, and best regards,

Even though I disagree with you on the efficacy of some things, like power cords and fuses, welcome. It's too bad you had to shut down the other thread but it was getting out of hand.

All the best,
