I started last week, and now I finished the cuts.
Now it's the easiest part of the job, the cut was a nightmeare, I didn't have the electric hacksaw so I cutted by hand with very good blades.
I say they'll be ready at the start of the next week.

ones using voice coils) are not all that dynamic, so I take this as the highest form of compliment. Keep the Nomex, they have
lower moving mass that also result in 1dB extra efficiency/sensitivity. Every dB enhances dynamics as the voice coils runs cooler.
BTW, nice pic. It's going to end up on the website - gallery.
What am I doing now? Working on a killer amp based on a Chinese EL34 amp - it will be 20W/ch of the purest Triode Watts
you have ever heard. In most rooms that will be enough power for the Elsinores to still go very loud. With this amp you will
really hear what a low dynamic compression loudspeaker system can do.
The method of connecting EL34 into Triode mode is NOT the usual resistor. Otherwise the Anode and Screen does NOT see
the same AC impedance, which they MUST.
Massive increase in dynamics!!!
The amp will also be fitted with a special module that induces Permeability into the output transformers.
Forget fancy armorphous cores which saturate at half power, this L.E.M. (Linearity Enhancement Module) means you get
the full power and low distortion of silicon/laminated steel and the high Permeability that even amorphous road cannot. Want
to hear low level detail? You've got it!
Anybody in Sydney (Australia) or nearby, want a demo? Just give me the chance!!!
It will look similar to this:

Elsinore MK3 build
Hi, just build my pair of MK3 some weeks ago. Kept Joe's design as close as possible with some minor changes:
- crossover is inside on the bottom panel, which is removable
- separate connections for tweeter and midbass/bass
- front and back panels are covered with 3 mm black acrylic sheets
- tweeter felt is made from 4 mm felt I had on hand, slope is more gradual
- tube is made from mdf and covered with veneer (i did not get adequate tubes in Germany)
Crossover parts are from Jantzen/Denmark.
Sound is outstanding. Hopefully more people will give design a boost.
