Title: Re: Nice AM tube? Post by: Opcom on October 03, 2018, 07:27:05 PM Maybe a trip to the local electric distribution company with a few bucks, for an old 2400V or 4800V pole pig with two HV terminals?
Title: Re: Nice AM tube? Post by: PA0NVD on October 04, 2018, 08:11:12 PM Sounds as a good idea, don't provoke me.... But I think that the pole pigs here in CR are all 19 kV AMfone - Dedicated to Amplitude Modulation on the Amateur Radio Bands
Whenever comes the time that I run into a power supply, I like to try the cathode/grid modulation with a simple power FET. A single 1200 V FET may modulate the tube running at 1500 W carrier |
