Yes, I realize the pot is backwards--and I am using it backwards--and I'll fix that.

The leads from the tube pins are:
1- dark blue
2- black
3- yellow
4- orange
5- light blue
6- red
7- black
8- green

Oscillator coil pin 2 is green wire. All greens go to ground. Tube pin 4 is an orange wire.

I started with the audio input because it's so basic that Phil's instructions do not describe it in exquisite detail. Would it be better to use the output for a 4-ohm speaker than the headphone jack?

Breaking the grapite slugs: I never had this problem before, but now the adjustment is very stiff (I am using the appropriate plastic hex). I finally figured out that I've been moving past the useful range, to the end of the threads. Then it binds, and when I try to back it up, it breaks. But it only took me 3 coils to figure that out!

Yes, the tube lights up. And the electrolytic caps hold a charge.

I'll fix the pot and see how it works with the speaker output. Then I'll do the voltage readings.

Thanks very much.
