Used the schematic and built one for myself using a roller inductor and air variable out of an old mfj-989.

Hi, I am working on one and only have a 320pf 1930 vintage variable capacitor. Coil I'm using is an air coil. I did the same setup with the Ameco AC-1 but get a little buzzy note on the receiver vs using other tuners.. I will try it on my homebrew shortwave receiver tonight...
I was thinking that if the value of the capacitor has something to do with the slight buzz even though the SWR was down 1:1 and the full watts was out. If that's the case on using a 500 and some variable then I'd have to get one or place 2 of them in series.

Which page are you viewing? 6L6 transmitter

Comments:
I built and used the same 6L6 transmitter and 5U4 power supply with a 300 ohm 40 meter dipole as my first novice rig in 1968. The schematic came from a Popular Science Project (I think) book circa 195? and  I used toilet paper rolls for the coil form. Brings back memories. Had my first QSO with that same rig. thanks,

Which page are you viewing? Transmissor com 6DQ6 para iniciantes

Comments:
   Prezado colega James, parabéns pelo seu excelente projeto deste transmissor. Já estou iniciando a construção deste fantástico transmissor para meu shack de rádios. Seguindo corretamente seu esquema tentando fazer exatamente conforme seu projeto.
   Construo artesanalmente meus próprios transmissores para "AM" sempre utilizando moduladores em alto nível, ( modulação em placa ). 
    Sou radioamador brasileiro, há 35 anos opero nos 40m em amplitude modulada, mas gosto também de operar um pouco em telegrafia. 
     Um forte 73, Nelson PY2NVD.

Thank you for a great website!
I am currently building Bob Heil's Pineboard transmitter from the January 2018 issue of QST. This receiver looks like it would pair up with it well. I believe it will probably be my next project. Thank you for the Fantastic documentation on it, I'm sure it will make the build process go much smoother than it would have otherwise been.
Thanks again,

I am W7KDL in Phoenix, AZ. I ran across your site from a link that someone sent me. I don't remember who. It is very well done with a lot of areas that are useful. I particularly like the "HotDXS workbench" section. Since 1956 when I got my K2RTI license, I have enjoyed building and using simple tube type circuits. So your "Workbench" section caught my attention. Keep up the nice webpage. 73 Dick.
