[quote user="Romy the Cat"]BTW, I was kind of saying it many times in past but I think
it high possible that it was no lost in translation. Anthony, if you are trying
to implement with your version of Milq the same multi-amping with line level

[quote user="kodomo"]Hey Anthony,Your project is going on track (and looks like a very good track)! Just a reminder about the room acoustics. You are talking about bass frequencies which are as dependent to the room as the speaker! Before installing...

[quote user="oxric"]Hi Anthony,I am amazed by the work you have accomplished so far and love your stands and horns stacks.Two comments though in term of overall esthetics although I realise that having spent so much time on this it may be too late to...

[quote user="anthony"]I have designed the 2 driver wood boxes and when I stack them and put them next to my horn stack in CAD they are just not as pretty as the steel tubes and actually detract from the aesthetics in my opinion. The main problem is ...

[quote user="Romy the Cat"]Here I share some thoughts about what you have shown. I will
share only critical and warning thoughts not because I have nothing but critiques.
All nessesary compliments for your planning come as a default and I do not

[quote user="Romy the Cat"]Anthony, I have an unexpected advice to you. Label all knobs,
testing points, input and outputs. Everything sounds to you very logical and self-explanatory
not but, so it was to me. In 12 years you will be looking at the ...

[quote user="N-set"]Very cool idea with a built in pneumatical (?) vibroisolation! I run a small company offering pneumatic isolation platforms for audio. I attempted totalk to various equipment manufacturers about building in such solutions into the...

No, I've not built the big woofer towers yet, but have some steel here to make the first few Cannons up to try out and measure and listen to to see if I can make the system work. It is essentially the same solution that Romy uses so I think I should...

It took a LOT of time in CAD using what I had learnt from building the power supplies and then adapting it to match the requirements of the rest of the system. I have decided to mount the DSET on the horn stack and direct connect the speaker cables....

...I think it has something to do with a small obsessive part of my personality, but as I have spent more and more time on this project I have wanted to do a better job as far as quality of workmanship and design and aesthetics are ...

Hi Romy,Minor question with hopefully a simple answer.In the DSET schematic you have a 12.1k resistor in the bias for channels B, C, D and F. I have some nice 12k resistors here (not 12.1k) that I could use in those positions...can you see a problem...

[quote user="Romy the Cat"]Sorry, Anthony,
I do not follow what you are asking. What does it mean “panel meter on the DHT channel”?
My DHT channel has a plate current matter. I find it useful but not truly necessary.
My sited at 38mA for years and...
|
|
Romy, do you have a panel meter on the DHT channel? I am currently designing the chassis for my DSET and looking at your schematic there is no panel meter for either driver or DHT. Just trying to figure out what would be useful to have in my amp.Re...

It is not a fear of forced ventilation per se, rather a fear of dust permeating the enclosure. You may have noticed that the power supply chassis' have been designed without ventilation holes on the 'roof'...this is to eliminate dust-fall into the i...

[quote user="Romy the Cat"]
It look like the project progress well. I have a little concern
about heat the will be building up in your PS enclosure. I do not know what
kind ventilation hole you have in there but be advised that it will be quite

Romy,Using the Fullrange PS I have bread-boarded the Fullrange amplifier...Turn off the lights and it looks much better.To my surprise (this is my very first amplifier build) everything seemed to work pretty much straight away. The voltages seemed r...

It looks good to me. As you can see I have left plenty of room to add a couple of more channels.The bottom level contains the power transformers and relays. The diode bridges hang from the the middle shelf and the chokes and filters are on the top ...

To keep with Romy's spirit of sharing his work, I have attached a file of VER 1.0 of the DSET Power Supply. There are quite a few differences to Romy's published schematics but it is basically the same beast. You will notice a lot of power transfor...

Now that I have tried it the CLD works wonderfully, at least to the knuckle test. There is absolutely no ring to be heard and it now sounds like rapping your knuckles on a very heavy solid wood door, but probably lower in frequency. Dull and soft a...

Hi N-Set, I am three quarters of the way through assembling the first power supply to power-up stage so I have not tested the "singing" as yet. It is something that I have thought a lot about. First and foremost I wanted a steel skin around the pow...

I designed up a steel chassis for both the Fullrange and DSET Melquiades. Here they are screwed together for the first time. Then I have made sure all the cutting and drilling has been in the correct places by quickly putting the parts in their pla...

[quote user="Romy the Cat"]A few days back Simon
Rattle brought but Berlin Philharmonic in Boston and blew my mind. I never was
a huge fun of Simon Rattle and the music was garbage (Mahler 7). We were
sitting accidently very close (Berlin extended...

The Bass OPT's for my DSET have been wound. We have come back to a 1000R plate loading and into 1R the 6C33C grid clips at 9.36W and 5.8% distortion. The -0.5dB points at full power are 5.9Hz and 5kHz.A nice result really, and about where I thought...

I do not use
tubed bass trap as I do not like the sound they produce. To have any more or less sensitive absorption
at 50Hz you knee to put a lot of trap in the room and they shorten reverberation
time at upp...

Do you have any photos of your experiments? I would be interested in the foam and how you are using it in the horns.Cheers,Anthony...

Wow, twins! Congrats Romy, that is lovely news....
