Post Subject: More data about the new Melq and some about the Super MelqPosted by Romy the Cat on: 7/28/2006
Well, Jim, it is time to say “Oops!” I told to myself do not make any posts early morning unit I eat a bagel but this mooring I disobeyed the rule. Anyhow, I do not know how I come up with 28.5V RMS. Defiantly it was peak-to-peak on the scope and I remember that I intended to get a correct calibrated number, so I did but, or I think I did…. but it hardly looks like anything mindful. The amp should be in 12W region, slight less then the original was. I juts feed it with 2.4V into 12R and my “true RMS meter” Fluke 87 said that it is 9.22V. Also, here is the feed directly from my generator that you asked.
Below are the square waves:
1000Hz
20.000Hz
100Hz
Here is I fed one channel from scope directly and another from amplifier. The wave that came form amplifier is located higher in all 3 pictures.
1000Hz
20.000Hz
BTW, boys, juts for fun… The Super Melquiades LF channels were made more powerful and it runs 6C33C at higher plate dissipation with a transformer with a single secondary, gaped for a double operating current with much more inductance and core mass. The LF channels was tested and “tuned” (enough current + enough voltage”) as 4.2V at input, which is quite a difference with 2.4V of the current fill-range Melq. Still, I was trying to run it at 4,8V that makes it far beyond 20W. Well, take a look what it does… , if you feel that the Super Milq LF does not mesure insulting then I would assure you that it sound much more interesting then it measures…. I believe those who heard it would not disagree…
