It is a very strange feeling, but I really feel how this entire idea should sound. I mean the 500W SET of the REAL SET driving a 12-14 cubic feet of sealed enclosure loaded with North Leviathan Driver.

In past when I played with SETs driving Aura 18” motors it gave a completely surreal feelings. We are not accustomed to SET power, we not accustomed to the underhanded bass excursion with a pure paper suspension… It was very different feeling and I remember that some things that I experienced during those days were very “interesting”, to say the least. If you remember the Doctor Gizmo’s idea of 1000W OTL via witch he indented to “hear the voice of God”? It is not exactly my intention but I remember at that time I experienced some very “interesting thighs” that would be a fun to replicate in a REAL full scale within an environment with a real-life reverberation time.

I never was able in my past to run the full “scale bass scenario”. When in past I intended to hear my “real bass prototype” I loaded the old version (not the new crappie one) of Aura 18” into an insultingly small 9 cubic feet enclosure and locking myself in my small bathroom I was driving it with Lamm, lowering it’s plate current ML2 (there was no Melquiades at that time).  The sound  of SET driving this thing was something very special, something that is completely not heard under the normal circumstances.

Really, it would not be so outrageously difficult to make an operational prototype around the GM2 tube. GM2 with 2500V on plate could make a beautiful 400W-500W SET. It can work perfectly submerged. If you remember Von Gaylord from California made his PP 200W amplifiers around a liquid cooling.

Unfortunately in his case the amplifiers did not perform well and as I could judge in the Gaylord’s case the liquid-cooling was make explicitly for photogenic sake and served only marketing purpose.

The 2500V on plate sound like more or less manageable as well. The guys out there wind 4000kV-5000kV transformers and for the project, considering that it should handle juts <50Hz it will not have many complicated isolated sections. Sure, this amp with crazy LF objectives will demand enormous inductance and the OPT might be a size of a refrigerator…. The nobler would be if someone would build this thing…

I wonder… how far would I fly to listen this amp…
