Jessie, congrats on the new *TEFLON* sockets. Did you do the cap shuffle, too, while you were at it? And what's this you say; you had to mill the sockets (or the chassis) to get them to fit? Tres droll!Now that your operating points are stable you...

[quote user="jessie.dazzle"]Since renewing all tubes in both ML2s, over the period of about 3-5 minutes, the V2 bias on one of the amps cylcles between .27 and .33VDC. Is this behavior indicitive of a defective 6C33C?[/quote] That is not good. Try to...

Jessie, this is a whole idea: do not get a signal into the ML2. It is NOT an operations sate but juts immediate testing. Do NOT short the ML2 input when preamp is connected to ML2 XLR inputs. By shorting the amp’s inputs you hear the inner-noise of t...

Jessie,
Unfortunately it is in my view it is absolutely imposable to predict anything juts based upon the CAD modeling. The entire criteria that you for founding the right positioning of your instantiation are wrong, at least in my view. You use the...

I would like to point out something that is going on here that I found truly remarkable.
For advanced people ho play with horns there is no second opinion that the vertical array, the Macondo/Cressaro-Gamma type of architecture, is THE ONLY one tha...

[quote user="jessie.dazzle"] 6dB extra? Relative to what? [/quote]
Relative to the reference level of my MF channels. Look at the Chenal “B” of the the amp's schematics:

[quote user="jessie.dazzle"] There should be no danger in running the S3s down to 500Hz; I am currently running a pair of S2s (same diaphragm as S3) down to 450Hz, 1st order, no problem.
The system is in a room that measures around 80m² with a 3m-h...

Romy's quotes in blue:Daniel J. Plach's quote in green:"...The back chamber mechanism is good. Are you planning to do the same in the midbass horn?..."Yes, it will be similar, but more robust; I have an idea for a locking-type seal, which I would pro...

Jessie, 45Hz horn with 6”-7” throat around AK151 driver is from my perspective is the best thing might be theoretically built around a cone driver. I really envy of you and if I had room I would unquestionably go for it; this is why I keep a pair of ...

[quote user="jessie.dazzle"] The AK150 and 152 are not new creations dreamed up by Mike; they were made back in the day by Vitavox but nobody ever talks about them and I have never seen either. See the Unofficial Vitavox web site; AK150 = Catalog...

Jessie-Good to hear from you. I am very motivated following your progress. Thanks for the inspiration.My room size is around 15' x 18' x 8'. At this point, I feel that a proper 60 - 70hz midbass horn is physically the largest I am realistically pr...

[quote user="drdna"] What was more concerning is today some 60 Hz hum also re-emerged in the system, sounding like a vibrating cell phone going off in the back of the room. It was interesting how it was sort of localizable, but the hum is annoying. A...

Jessie, you can imagine that the output tube was hot at 59 watts. FWIW, I never go a month without checking OP, usually within 2 weeks, and in this case I had checked it less than a week before.The tube itself is the heat source, much hotter th...
|
|
Jessie, another thing is that there does not appear to be an actual "standard" tube pin diameter for a given species. Add to this the mediocre initial quality of the Lamm sockets and you have a less than ideal situation to begin with that cannot im...

Thanks, msaudio, for sharing your experience with Aura and Hartley. I do not have Hartleyes. I heard them I think twice but person the people did not try to get out of their playback anything that I care, so it is hard to say anything. In contrary I ...

We should define some borders here; LF, when you have an UBH, should be from around 100 hz down to 30 hz, where the last fundamental tone of an instrument is played. ULF should be under 25-20hz.I would say that a driver playing 25-30 hz should...

Jessie,
I was trying to evaluate the gain of my amplification in respect to larger room and again was thinking about your case. I think something that you do it not correct. You are complaining that you have not enough gain in upperbass, but I...

Jessie, we keep meeting at the same intersection. Like I said before, I agree that direct radiators suck, for all the reasons you cited. But if what you say about horns is strictly and completely true, then does it not follow in spades at ever lower...
