They weigh about 5-6 pounds per. I was a bit freaked out when I picked up the box, since I was only expecting one.

Yes, I am happy with them.

Questions:

1) Is it possible to use these in our amp build. I really hate to send the extras back if we're going to use them later on. Can you design an amp around these? If so, I'll keep them. I know Heyboer is a small company and I really hate to see them eat the cost. They were doing us a favor in the first place.

2) There are lost of pretty wires hanging out of the Tx. Is there a conventional color scheme for the secondaries?
