Here are some pictures of my latest creation for Tyrell

A #45 tube driven by a C3g 6BY5 rectifiers Lundahl transformers.

 

 

 

 

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

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...:evil:

post #4896 of 10163

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?

Gorgeous looking amp, well done Glenn.

Tyrell you are very lucky.

 

One of my headphone amps is also using transistor control for the heaters (2V to 10V, user adjustable), it's a good idea.

RWA also use D-Class in their designs and so do my B&O monitors.

I do agree with Glenn, no point for small powers.

 

Eric I can see the Muses inside Tyrell's amp.

Goodness. I don't touch my computer over the weekend and look at what I miss. Good thing my phone alerted me to Stavros's email.

I'm kind of at a loss for words to be honest and don't know what to say except its beautiful and thank you so much for everything Glenn.

One thing im curious about though...Are the caster feet not on it yet or is that shag carpeting? :-)

With autumn just on your doorstep, you're gonna feel right cozy with your new '45.'

Good clean layout both inside and out.
