350.5 modding the amp to work in more class A

[jfrago]

that's funny.

I am am still listening to the class a amps to see which one is for me.

thanks again.

This whole thing of "when an amp leaves Class A" is a red herring.

We get so many questions about it that I'm preparing a new ad for
the magazine devoted to the subject.

The Answer: forget it!

I agree. It's not about what's in the spec's. It's about what makes my feet move and that's what I listen for.

Cheers!

class A

I am not an engineer but I can say pure copper heat sinks would work it this case. Maybe titanium or any fancy material which is less affected by heat would also work. However, there is demand for one box, a class A stereo amplifier rated minimum 100 watts in 8 ohms.

If you have a bunch of copper heatsinks just sitting around gathering dust, I'd love to have them. Copper conducts heat better than aluminum, but as a metal it's more expensive and doesn't extrude in fancy shapes the way aluminum does. It's also more chemically reactive; aluminum just creates a skin of aluminum oxide (aka sapphire, ruby, corundum) and hunkers down for the long haul.

Nah, copper works the same, and even without having to do anything to get the oxide layer

Aluminum looks better when anodized than copper with an oxide layer though.

Anyhow, just reach out for a few thousand dollars, and you'll see for yourself

Amps as art?

I remember seeing someone's effort at heatsinking with a rather large sheet of copper. I would almost bet there was commercial interest in an art work pounded out of a sheet of copper that was also an audio amp. Wife Acceptance Factor being what it is.... And the decorative art market, not to mention the absurd numbers of audio equipment sold on the basis of "looks" alone.
