Yeah, yeah, I meant 2U you bunch of nit pickers. Bottom line, as Naaman said without some fairly special tools the pins can be problematic to remove. Maybe not a big deal here, I have only seen one failed sigma22 and that was under exceptional circumstances.

The 2" versions all come with pins as well. One other thing to consider is that moving to larger sinks doesn't do much to help with junction temps and may complicate the casework quite a bit. A 2-1/2" sink eats up a lot of vertical real estate, I'd recommend going with 2" so that once mounted to the boards you can still use a 1/2" standoff and have some clearance in a 3" (1U) chassis.

Bummer Colin, but keep trying. I'd be surprised if there's anyone here who hasn't gotten a letter like that at some point.

Crikey, I'll probably be in for a couple sigma22 kits w/ upgraded caps and heat sinks. If I may make a suggestion: see if you can get the heat sinks without the pins in them. I really dislike soldering heat sinks in place on builds like this. It makes them very hard to remove if you have to repair something. Also, removing the pins is a reasonable sized pain in the ass too. I just got done doing it to a dozen of them for a beta22 project I'm working on and it was not fun.

Don't worry, his posts will be rapidly disappearing throughout the day.

Spending $900 on a used output stage doesn't make any sense to me any way you put it, sorry. The purpose was not to buy a project as far as I could tell.

All thanks should be directed to en480c4, my love of Rasputina is his fault.

Happy Birthday Naaman!

I'm not sure I can see a way to do this that doesn't strike me as just wasting $$ unless you're willing to shop used. All of the prepackaged systems I've heard have left me seriously wanting. And for HT I'm just not that picky either...

Other than the sweet hookup that Dan almost assuredly just offered I would recommend having a look at Sager Notebooks. Oh and if Dan just hooked you up as I suspect he did you should shop quickly, the last email I got from them had some scary good deals in it.

BTW, I fixed the title of your thread.

I bought two 3"x3"x12" pieces of turning stock, one Mora, one unknown.

Oh lord.

It should, yes.

Good plan.

Ok, how about my tractor costs as much as some cars, does that make it anything other than an expensive tractor? No, it does what it was designed to do exceptionally well and I don't expect it to be a car. While headphones require less power they are also FAR less forgiving of noise. It also requires an entirely different design to deal with the varying impedance/load that headphones can present to the amplifier. Look, if you think the 307A is expensive that's a fine and justifiable position to take. But to back that statement up with is completely in appropriate. You're using power as the basis of your comparison. You should have stopped with "my bad".

Comparing the cost of a speaker amp to a headphone amp is worthless. Is the 307A expensive? Yes, but you're paying for a hand built, limited production item much in the same way that you would expect to pay more for a Bugatti than you would for a VW.
