Wyn is working on a new power amp...

[J!m]

To anyone following along, Wyn just posted a schematic, frequency response and phase curves, driving electrostatics...

(it's pretty damn impressive)

So Jim, I read through what Wyn has posted on the PA project. Is the power out going to be to your liking (60WPC??). It would appear that the noise figures are very good. I see he had to slow you guys down for wanting to get a Power Supply fingered out and he didn't seem quite ready for that yet. You just can't hurry these things.........

I think 125 into 8 ohms and yes it’s a bit small for my taste.

Power supply parts were for the prototype, not necessarily for the final product.

Too small for me too but I wouldn't mind building a small shop amp but after hearing how big the cooling scheme is going to be, I may look around for a mini amp.

That cooling was based on 500 watts class A.

it’s less wattage and class A-B.

I'll follow along. We'll see how compact the unit is going to be.

Copper heat sinks would be half the area of aluminum ones.

When I was looking at heatsinks for my Load Bank, I saw the price of copper sinks......... HOLY CRAP...................
