Hi Ted  
Is this your amp or someone elses?

The idea was conceived by a guy named Brian Thompson, who worked with Joe to define the basic requirements. Then, they asked me to join in to work out the details of a high Z speaker and its drive requirements. As you noticed, the thing looks like a ham radio transmitter, but we three are all ham operators, hence the look and the use of the 807's in parallel running class A with a pretty high B+ on the plates. Interesting circuit. Bottom line, I'm just a consultant and supplier of the speaker.  
It's been a fun project for the past year or so.  
We also have some other projects cookin'. Apparently, they already have a half dozen of those amps sold and it is going to be evaluated in an upcoming GP article.

Maybe those input connectors should be PL259's!

259's... darn, I should have suggested that.  
I did ask them if they were going to suggest using a grid dip meter to tune it up... ha ha...  
Brian says they are getting a useable signal from the JW15 (that's what I call the speaker) from 20hz to 14Khz. I'm used to building speakers that tank at 6Khz, so that was a challenge. Like everything, it's all about energy.
