Pushing air v. pulling air
Two points:
1. Pushing air worked well for me, on one of the biggest "heat generating" amps (the Pass F5). See details at: http://www.diyaudio.com/forums/pass...-build-beautiful-music-different-drummer.html
2. We probably need to take any further esoteric discussions of air flow and thermodynamics to a different (new) thread, and retain this tread for pictures of Pass Amps. (Or else we will upset the enthalpy of the diyaudio site!)

Enthalpy is a measure of the total energy of a thermodynamic system. It includes the internal energy, which is the energy required to create a system, and the amount of energy required to make room for it by displacing its environment and establishing its volume and pressure.

Just to dilute your smart thermodynamics arguments, let me post my "F5 invasion" photo. If you don't mind
I like the amount of entropy visible on the carpeted floor workbench
I think we have all been there: you work on your diy project on the floor for lack of a convenient bench and 4 hours later you get up to find your back and leg muscles are all thrown out of wack.

Ain't that the truth.

Actually, entropy was quite low: it was only a couple of ways I could place it on the floor being able to connect everything ;-). 4 hours?! With my back and knees now, it is more like 15 min

6L6, et al..... My thanks, Jim. I KNEW I didn't sleep through those three graduate courses in thermodynamics and computational fluid dynamics they forced me to take(!).
Yup. I said enthalpy....and that's what I meant--I was referring to the energy of the "photos of your Pass amps" thread. Q.E.D.
OK. Onward. Upward. Before we get into the glorious and incestuous details of the Carnot Cycle (guaranteed to put you to sleep!).
Danger, danger! Now we are getting into my academic background...! What's next??? Dirac transforms and Schrodinger equations of probabilistic quantum mechanics.....???? Run. Run away..... Quickly...... Nightmares abound!!! Do not enter!
In your pic, we can't see your knees, but we can see your latex gloves.
Schrodinger equations of probabilistic quantum mechanics or not - It's good to see you back on the boards.
Thanks, Bob..... a major move is never relaxing, but I'm settling in. I hate to be "almost on topic" in the thread, but it follows the "build it on the floor" topic. I had a great home lab in Colorado. I had to take a more restricted (and wife friendly) solution in Florida (no basement!). Some pics of my solutions. (Maybe we need a general DIYaudio forum describing "home audio workshops, complete with photos....!) That last photo: two matching 0-50v, 20 amp tightly regulated power supplies on the floor.....something that every Pass DIY'er should have handy!
