Hot damn, that is gorgeous mate.

Certainly seeing a lot of very nice attention to detail.

Itís looks like a high end retail amplifier straight out of the 70ís (give or take)

Any chance you might have a higher resolution of that shot of the internals? Happen to have any more photos of it? Another of the inside would be rad.

Regardless, congratulations mate.

Wavebourn,

Were those KT66s?
Or Kt88s?

I am glad to see some of your amps going down under.

I hope you are being paid at least a little for your labor of love.

You have settled on a good topology, and seem to be able to make it work well, for just about any Beam/Pentode output tube.
Nice job!

Yes These are my biggest 1024x768. I don't have bigger ones. Amplifier on LND150+EL42 (hybrid version).

Thank you.
Yes, my prototypes are getting popular, and each new one improves usability due to suggestions from people who buy them. Here is what he wrote:

"Thanks to Anatoliy for all of his help and patience creating this combined Headphone/Speaker amp.

The Edelweiss absolutely delivers on it's promise of high end sound on a budget.

This wee amp's 6w can drive my 96dB speakers to well past normal listening levels and sounds fantastic.

The switched headphone power and speaker switching works perfectly and I'm still amazed at how quiet the amp is on any output, dead silent!

The Edelweiss is also a tube roller dream, I have tried - EL34, KT77, 6L6G, 6L6GB, 6L6GC, 5881, KT66, KT88, and all work perfectly. My favourite is the KT66 pictured."

I almost ready to start production business. I finalized 2 things that I am going to manufacture. A 4-input preamp capable to deliver 20 mA peak output, with headphone sockets, so it can be used as a headphone amp for ordinary high sensitivity dynamic headphones.
And a speaker/headphone amp as pictured. It has 4 position output switch on the front panel, for speakers and 4 output levels for ordinary dynamic and low sensitivity planar magnetic headphones. On the rear panel it will have one more 4-position switch, for different damping factors, from "current drive" to heavy servo-damping by negative output resistance, to better match different speakers like open baffles, horns, closed and ported speakers.

Here is the preamp on the floor driving my Gubernator-71 amp:

It DID take me a little while to realize that's what you wrote!
