[quote user="oxric"]Hi Romy,First of all, as things stand in the sketch, the mast sits atop the legs, a horribly precarious position given the weight that will be applied away from the centre of mass of the structure. This sketch is an early ...

I wasn't trying to critique Bert, or even get into an in-depth critique on the Swing, more Compression Driver configurations -- vertical vs. angled, and coaxial, (and maybe other factors which affect Sound). But I'm more and more real...

hi alla owner of the Swing of bd-design describes his listening experience with his new speakers at home, i think that deserves attention :http://www.bd-design.nl/forum/forum_entry.php?id=11829he could not be more enthusiastic. i believe him, as i ha...

romyi never heard before regarding this technique of push pull, ore isobaric design. i searched the net, and i found it very interesting.That means when one driver cone is moving out of the enclosure, the other is also, but, due to the way they are m...

Romyi will start building my first hornspeaker, going from theory ( surfing the net ) to practice. i am not pretentious regarding the result, i am very aware of my knowledge limitations and lack of experience, as i am just in the beginning. but the w...

[quote user="CO"]I have tried a BMS driver a while ago and it was really bad.
About a year ago i heard Berts setup at his house and it did not impress me... It was also with the coaxial BMS.Not much depth or resolution. Did have alot of power though...

Thank you Romy! Actually I've realized that when I wrote it I rather ment dynamical stability then frying the outputs. But in proper PP the even order harmonics are strongly surpressed, sothere should be no or very little change of the output OP due ...

The 6C33C preamp? Hm, this is bold. As I see you use it as a single stage buffer with only one 6C33C and couple output with a transformer? I head the Germans built something like this but I never heard it or saw it. I do not feel a need for such ...

[quote user="serenechaos"] I started thinking about all this due to Bert Doppenberg's Swing I heard @ RMAF. He said some people prefer it to always be vertical, but he prefers it with the mid and high (co-axial horn to the outside, and the bass...

Yes, I did not realize that the price of £225 is for a PAIR; usually price is given per driver. I guess the £225 per pair is not and of the world but I still insist to pay 65 cents per 1 Euro as it use to do… In past I n...

Delet if not proper topic. Was wanting to experiment with 6e5p driving lifeless speakers. with possible 100v swing i'm guessing way to much for regular garbage amps. What are peoples ideas for lowering output v (to like >5v?) with out destroying...

I know there is no reason to describe my view about high end audio but i do not know why i am interested to do that in this forum.I think we could categorize audio systems in 3 level.Level 1 is a system that make you sad in long listening session bec...

I do not know what it is all about as I’m under impression that it you socialize with people on dB-design forum then they will be more responsive about your excitement. I’m not quite sure what the SWING is all about as the guy mentioned and descried ...

Thanks for response I will e-mail after the holidays. i have begun exchanging mails with the builder and I think I can swing this project, financially speaking.R Weissman...

Romy, I tried out a 6e5p as a driver tube in a PP 2a3 amp (was using a 7788 for driver). Well, knock my socks off! The amp went from 6 watts to 8 watts! Distortion dropped a tad, but mostly it was more signal swing. I could dr...

Romy, Some very good points here... if I downloaded the correct schematic from your site for the 6-channel Melq amp (also has the term DSET in the title) then you have created a 6-channel SET amp with built-in crossover points. Your first ...

Driving an 801 or 10Y with another DHT would be tricky. The driver stage would need a Zout of <400 ohms. A 2A3 might do it via a step down interstage although making a good interstage that'll handle 60mA will be difficult. A 45 at near maximum rat...

This trick of disconnecting all the grounds works, depending. . . I am not a happy or unhappy, as the case may be, PP owner, but I know this to be the case anyway.Now, is everyone aware that which way the plug is mounted in the socket make a differen...

Thanks for the extensive reply. I wish I knew exactly the use the preamp is doing of them and if they could be safely replaced by those alternatives you mention. I believe they're regulators within the power supply. The problem with them is not burni...

N-Set, this tube does look interesting, in that it mostly fits your stated theoretical desiderata, save the true triode part. It will also be interesting to see how you swing the drive voltage in only one stage, and how you will from there arrange a...
