[Boatanchors] Seeking Transmitter Design Suggestions

[wa9wfa]

Hi Rod (and List), Thanks for your advice on that circuit design.  From your comments as well as Mark’s and Bob’s, that 6AG7 and 807 appears to be a solid combination.  

Bandswitching concerns me somewhat as I’ve not built a transmitter before.  My first radio project is/was the HBR-13 and it uses plug in coils.  I appreciated the simplicity of that arrangement versus the seemingly complicated switching.  Maybe it’s not as bad as I envision it.

Many thanks for your comments.  I will PM you.  73, Scott WA9WFA
