That's because you built it like a tank
:tresbon:On some of the first photos you show the octal-sockets with mounting-rings attached for under-chassis mounting.
You actually ended up with top-mounting.
Is there a reason for that?
Personally I prefer out-of-sight mounting but yours look OK as is.
Any thoughts on the actual 6V6 schematic?
...or on the two remaining amp's (Mid & Bass amp's)
I can't help thinking if the 'small' Treble-amp is a tank ...what's waiting?

Unfortunately, the octal sockets only work for under chassis mounting if the plate is not so thick, the plate here is 1/4" and it is too thick to bottom mount. Was a bummer, but it's not so bad after all, if I didn't do it this way, you may have seen the raw aluminum.
Yes, I have had it selected for some time now, just never gotten around to scanning it.

Perhaps monoblocks. Definitely something big.
The midrange amp is already built, that's the F5.
Bass amp is going to be either class AB, or class D probably at least 200WPC.

Looks great!! Excellent work.
I don't believe there are supposed to be wires sticking through the middle of the tube sockets 
Looks good. I kinda like the idea of the RCA inputs on the back on the same side as the speaker jack. Sort of makes sense which input feeds which set of outputs. I'm also assuming the posts are for 4,8,16 ohm taps ?

Yes, I wanted to keep a switch out of the signal path so I have individual posts for 4, 8, and 16 ohms.
Thanks, coming from you that means a lot!
looks like you are ready to melt some lead...
Since they're local, you should give Front Panel Express a try sometime. They did a fantastic job on a top plate for my DCPP amplifier.

Well, I didn't notch in the back plate, so I have to epoxy it, but the metal has a very slight bend to it lengthwise, so I have to clamp it strongly on both ends, and in the middle.
Cure time is 6 hours! Guess I won't be finishing the wiring today.

Yeah, strong as ****, I think it is 2600psi of pull strength, so if my math is right that's about 156,000 pounds needed to remove the back panel!
Here are some photos from today.

Yeah, if I had slotted it in like the top plate (top plate is not glued in, just held in by accurate cuts) it would have been recessed which I thought wouldn't have looked as nice.

Certified Crazy.
From where did you source the ceramic terminal strips?
Gorgeous woodworking, as always :thmbsp:
