[quote user="jessie.dazzle"]Having said that, I notice no difference when switching to battery when using a laptop model to run the external drive of my music server setup, but this is possibly because power may be routed "through" the battery even w...

[quote user="jessie.dazzle"]I just ran the calculations again and came up with a figure of 13.8 cu ft (for a QTC favoring transient response, not lowest F3). Then I measured the boxes and they do in fact come out to just under 14 cu ft, once wall thi...

[quote user="jessie.dazzle"]You might find that you don't need that much power.When I first built the ULF channels I assumed they would require loads of power, so I bought a single, mono, 1KW class D amp to use in testing. Then I tried driving them w...

[quote user="jessie.dazzle"] What am I saying? You might consider building a pair of "end of life" lower-bass channels now…[/quote] I would like to accent this point again. The "end of life" lower-bass channel in my view is not some kind of very well...

[quote user="jessie.dazzle"] Assuming one will not get anything under 50Hz (usable) from a 40Hz horn, I interpret the mission of lower-bass channels in the context of a horn system as follows….[/quote]
Hm, this is a bit tricky with bass. A pla...

[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...

[quote user="jessie.dazzle"]A possibly dumb question here: When you and Paul give figures in milliamperes, where are you measuring the current (at what points), or are you extrapolating the figure? [/quote] The 6C33C current is measured in mA. The wa...

[quote user="jessie.dazzle"]Consider treating the problem at its root.Why not build a simple dedicated PC, running Server 2008 with a RAID array? I recently added a RAID 10 array (8TB, striped and mirrored), to an HP workstation... The result is fa...

[quote user="Paul S"]You have said that there are no "good" 6N6Ps; but are some physically constructed better than others?[/quote]
Nope it was not what I said. I said the all 6N6P are equal, at least among those that I have seen and there are no rea...

I'm glad you had the opportunity to look into the G10. I find it to be a very intellectually satisfying material, which (to this sick mind) is important. G10 is a material that reminds a person of cleanliness, stability, perfect cons...

[quote user="jessie.dazzle"] Your latest post got me thinking in a sort of incomplete way about how you might locate the injection channel... If you consider tone as a harmonic of the original source, then (depending on the order of harmonic) it may ...

[quote user="jessie.dazzle"]Do I understand correctly: AG used Fane 8Ms in the Trios upper bass horn?[/quote] Oh, no! AG in Trio’s upperbass horn used similar 8” driver with 103 sensitivity. That driver was bad and it made me to look for a replacemen...

[quote user="jessie.dazzle"] I do my best to remain ignorant of the price for which I sell off the hours of my life. (Btw, I'm not a software engineer; I design cars). Yes I could pay someone to do the work, but I'd rather put the cash toward the pur...

[quote user="jessie.dazzle"]For your rear chambers, as they will be adjustable, it would be smart to go with a max volume that is larger than the max you estimate to be necessary. [/quote] The size of rear chamber is something that dials in the compo...

[quote user="jessie.dazzle"]
I just poked around on eBay and it seems the 6c33C-B tubes are not so easy to find. There are however plenty of the model 6S33S-V. My understanding is that this is supposed to be a more durable version, intended to...
