Fun. Good to know. My alleged 15K resistor (as marked) measured 12.5K, and ironically, I, too used a parallel resistor and ended up with 8.4K. My LO was then good to about a receive frequency of 600 khz before all reception stopped at lower frequencies, because the LO quit. But right now, the LO has quit totally (again) and the receiver is dead everywhere. 

I sometimes wonder how the osc tube would respond to higher B+.

Anyway, I’ll get back to this sad little oscillator this weekend.
