... I like the chassis vents and tube cage.
I don't know, but I think that cage around the output tube and rectifier was just for the european market (that was a euro export amp shown at the test stage). Product safety regulations are more strict over there; the exposed larger tubes present a burn hazard to children.
I'm thinking that won't be present on the US version (besides, we usually say, "I told the boy not to touch the stove, but he had to find out for himself...").
Are they doing that to keep the solder out of the tube sockets pin holes? Even so you'd think they would do that last, wouldn't you?
To understand what Doug is talking about, you need to plug a tube into a loose socket, not installed in an amp. As you insert the tube, you'll see the pin solder lugs wiggle all around. Therefore when you build an amp, if you solder all the wires to the sockets without at least a sacrificial tube in the socket, sometimes you will have the connecting wires holding the lugs in a manner that makes actually inserting a tube pretty tough. Placing a tube in the socket before wiring insures things will fit as they should later.
$999 for the Vibro Champ.

Me thinks pretty competitive.
Hoffman's old axiom was you can buy an amp cheaper than you can build it. For once, we have here an amp you can build cheaper than you can buy it, even after the "sale price".
