How hot is too hot?

Where's the problem? Sounds good to me... ;D

Just kidding. But more seriously, why would the chassis need to be aluminum, rather than wood, like the other kits? And I was serious about putting aside the film caps. I think your approach of putting good electrolytics in the kit, and then letting people choose whether to install film caps (and if so, which ones) is the right way to go and keeps the cost down.

As for the build time...this is a hobby. Putting in a couple of days is but a drop in the bucket compared to the time I have invested in this hobby.

Hey Paul,

You have to realize that when I put forth ideas like this it is not meant as a product suggestion, just a what-if for somebody with the design chops (definitely not me at this point) and the motivation (and of course the wherewithal.)

BH amps are just great as they are though of course they have also inspired many an over-the-top modifications as well.
I really love the crack as is with a couple of the common mods and really don't have any motivation to build an all-out version -- I'm just not that fanatical about my headphone listening, but I do like what I have and with the 800s, it is to my ears, as good as I'll ever need.

No, you guys just keep doing what you're doing -- it's already the best thing going.

Presuming it's a finished product, an aluminum chassis travels much, much better on the big brown truck.

Yah, I got a 'what if' gene too. When I start thinking about something, it starts to spiral into space. But that is a really good thing because I can bring back towards earth until it starts to make sense again. This actually is one reason I read in this forum. The ideas are great(and usually rational). It gives something to toss around in my head.

After 2 hours of self heating:

Transformers / inductors / Resistors (except sand cast) should be cool enough you can touch them (watch high voltages!) for 3 seconds and not cuss. (< 60 C )

Caps should be barely warm. You could hold them or if they were baked potatoes, you could eat them slowly.  ( < 40 C)

Sand cast resistors can run slightly hotter than transformers. The problem is, they heat up parts next to them.  (<70 C)

V-S, I like the unit of measure, and not cuss!
