    The Pine Board Project begins building the 80 and 40 meter AM tube transmitter on Ham Nation this week. Join the hundreds who are following the hundreds who are building this two band transmitter built on Pine Board. Put Ham Nation in Google and follow the show on Leo Laporte's TWIT network each Wednesday at 8 Pm, CDT. All of the video clips and diagrams are also at Warm up those soldering irons and join in the fun.

    I love this, I am a builder myself.
    Love to see the schematic.

    I recently rebuilded the Marconi R1155, was great fun.
    Check it out on my website PD3WMZ.

    Tell what you think.

    That's pretty nostalgic, and reminds me of my first transmitter that was on a piece of plywood it had a 6L6 tube.

    Just finished my power supply this week, I am looking forward to seeing the transmitter parts list and schematics when they are posted

    Would make a good retro kit.

    Was just wondering "hope you dont get mad" why such HIGH voltage for a starter project? I know some people who are very interested in this project but, the high voltage aspects of Tube technology scares the hell out of them. I pointed them to some alternative projects with transistors but, they still wish they could follow along with the show and your project.

    The 120VAC mains supply is more lethal than the B+.

    How on Earth did so many new hams survive the tube era? </sarcasm>

    Thanks, Jeff. thanks for following the Pine Board Project. We constantly talk about the high voltage and it is something that every builder - SS or vacuum tubes shoudl respect and know about. We are able to teach the entry levels much more about circutry with vacuum tubes.

    Stay in touch, Jeff

    How right you are, Jeff. It is something that is a big part of the Pine Board Project - teaching some respect of
    circuitry and with building on Pine Board, one can actually SEE and trace the circuit from the great drawings Gene W4IQN
    is doing. Thanks for being with us. Stay in touch.

    Your power supply looks great! Keep up the good work. Just respect the high voltage and I see you have a cover on the HV terminals. Good one ! Tomorrwo night is transmitter night.... see you on the other side of the screen.
