  I am wondering what is in it to require the chassis to be that tall. I'd hate to have to return the amp for repairs or upgrades.

Best answer yet!

Wrong it's Apollo and the Muses pushing the electrons and adjusting the bias current.
 
And for that price maybe a few more Gods and Goddesses.......

They are Elf Condo's......

Here are some pictures of my latest creation for Tyrell

I know there is some SS stuff in there I should hang my head in shame

hehe..."Come on down to Glenn's Hybrids!"  

 
It looks gorgeous!

I laughed out loud.  
 
Looks great, though!  45 tube HAS to be great sounding with headphones.

The SS stuff is just for voltage regulators for the filaments of the 45s
If I had more room I would have done it with chokes and resistors.
A active voltage regulator is the only way to get rid of the ripple with
out using large parts. Still needed a heat sink to get rid of the heat
from the regulators barley had room for that.

and I thought you were going to point out the Class D modules under the 45's...

 

[2359glenn]

Class D now there is some good sounding stuff for somebody.
 
I was going to make some 100 watt per Chanel MOS fets driven by
tubes.  Running class A creating allot of heat.
But getting custom made heat sinks is a problem. Still thinking
of a smaller version for headphones sure would drive Otho's easily
though.

Wyred 4 Sound is making some really well regarded Class D amps....The last 10 years have seen some great advances in that technology. B&O seem to be driving a lot of the R&D there.

My latest JBL monitors that I just received uses class D amps internal. Much lighter and less heat generated than class AB.

I don't really see the point of it to save electricity how much power is waisted with
people listening to music. I guess big amplifiers can run cooler but on small scale
what is the point.Just to prove it can be done and sound good too.

Glenn, very nice indeed. Your designs keep getter better and better and bigger--like my belly.

Great way to close out Summer 2013... nice effort! I'm looking at the bubble wrap and suddenly thinking about the year-end holidays. In the second pix, what cans do you have jacked-in? Do you still have the LCD2s on hand for this amp?
