Still off topic, I built a one-tube regenerative radio from a kit while in Australia in 1990.
Maybe a dozen or so electrical parts in all, handwound spiderweb coils, etc.
  It has outputs for a high-impedance set of headphones, and a matching transformer for 8-ohm headphones.  With the "good" Sony headphones, it's actually loud, and with "nothing" to degrade the audio, it has a purity that sounds much like studio monitors.
It shows off how much distortion actually occurs in the typical audio circuits ( and various flavors of AF detection).

When I've plugged it into a good Hi-fi amp, it's hard to believe it's AM.

Was that a kit from Dick Smith Electronics? I saw that at the time and didn't bite, and now I wish I had.

No, the Ballarat Radio Museum  somehow bought an old warehouse in Melbourne  full of old radio parts, and had put together a kit with a wooden base with a bakelite top, and one Marconi wireless company triode.  If Dick Smith ever offered this kit, I didn't see it. It was all pretty much New-Old Stock parts, and when I got home to the US, I rewound the coils again with genuine emerald green 1920's litz wire for the perfect look.

They called it the Unidyne. It will drive a horn speaker OK on a really strong signal.

Wow, that sounds awesome! If you ever decide to put photos of that online please post a link here!

Also, back on topic: Has Clear Channel (or anyone) done any tests to determine what effect an HD power hike will have on the audio quality of the analog channel? I'm betting it won't sound very nice!

Heh... According to NPR Labs numbers we 'only' loose about 171,000 potential listners of our 667,000 potential.  Go ahead and sign me up for two! NOT!

I mean... Doesn't everyone want to loose a quarter of their audience overnight with a finacially costly flip of a switch?  Any takers?
