Can someone on the list send me a photo of the "original" plate choke on the BTI LK-2000HD? I don't know if the non-HD is the same but if so that will of course do. My choke looks like it's been tamp

I have a dual (split-stator) 20-100pF air cap, 0.040" gap (so ~1500V) I need a single 15-50pF, 3000V for a tank tuning cap. So is there any reason I can't simply series-connect the split stators and

I would say that, considering the idle plate dissipation is 260W/tube, that some color would be expected. _______________________________________________ Amps mailing list Amps@contesting.com http://

My recent experience certainly hasn't been the same. The FCC seems to have become quite arbitrary. Example 1. cellular base station emissions are supposed to be -65dBc at a specified frequency delta.
